Why Would Ancient Astronauts Visit Earth?

I continue my contemplation of the kind of evidence that would convince me of the truth of the ancient astronaut hypothesis. This week I consider the question: why did the come?

Last week I began to explore the question: If there really were ancient astronauts, what kind of evidence would we find? (see http://dynamiclethargyfilms.ca/if-there-really-were-ancient-astronauts-what-kind-of-evidence-would-we-find/). I started on a new project this week; it is more of a writing exercise than something plan to share, but that depends on how it turns out. I did some more thinking about the ancient astronaut hypothesis and pushed a little further ahead with my exploration.

Why did they come?

I think that the  reason ancient astronauts would visit Earth would have an effect on the kind of evidence that we would find. I came up with four possible explanations. There could be others that I didn't think of, so I am open to suggestions.

Resource extraction

Could they have come to obtain resources? This idea was explored in the movie Avatar http://en.wikipedia.org/wiki/Avatar_(2009_film) from the perspective of the alien visitors. Of course it does place us humans in the role of the aliens.

I think that this is unlikely. Materials of all kinds are spread throughout the Universe. With the vast distances and resulting cost of transportation, it is hard to imagine anything that would be valuable enough to extract and ship to other solar systems.

For example, it appears that vast quantities of hydrocarbons exist on other bodies in our own solar system. It is believed that the volume of hydrocarbons on Saturn's moon Titan far exceed what exists on Earth. See http://en.wikipedia.org/wiki/Lakes_of_Titan. It is far beyond our ability to extract this resource and bring it back to Earth now. By the time we develop the kind of technology that might make it worth while, it is likely that the technology would make hydrocarbon unnecessary.

Nevertheless, let us assume that this was the reason for the aliens to visit. What kind of evidence would we find?

One type of evidence would be the remains of resource extraction, such as abandoned mines and waste heaps. The extraction would need to be on a very large scale, and so should be very obvious.

Another type of evidence would be the rarity of resources that should be abundant. If significant resource extraction had occurred, then those resources would be dramatically depleted. This might not be immediately obvious. We usually assume that the way things are when we find them is the norm. Only later research would unveil unexpected rarity.

I am not aware of any evidence along these lines.

Colonization

Could they have come to colonize? Many of our own science fiction stories postulate humans setting up colonies on other planets. Ray Bradbury's The Martian Chronicles

is an example of this. http://en.wikipedia.org/wiki/The_Martian_Chronicles

The experiences of the natives of the Americas and Australia under European colonization does not paint an optimistic picture of what humans could expect from alien colonizers. The best evidence for alien colonization is that humans would at best be a marginalized minority and at worst we would be extinct. Neither of these seem to be the case.

It is, of course, possible that an alien attempt at colonization failed, which would let humans survive. If that were the case, then the evidence that we might find would be the remnants of  alien technology.

Since the aliens would need a technology far beyond what we have now, any remnants could well be beyond our ability to recognize. In any event it would be beyond our current abilities to create.

Although there have been claims of advanced technologies found in ancient cultures, I have not heard of claims of technology that is beyond our current capabilities. The evidence would probably not be some isolated technology, but would involve a wide range of technologies. The evidence would not be ambiguous.

Scientific research

An example of how scientific study by aliens might go can be seen in the television docufiction program Alien Planet. http://en.wikipedia.org/wiki/Alien_Planet

In this scenario, the aliens would only be interested in the study of Earth, and would likely limit contact. This would mean there would be limited evidence of visitation. The primary evidence would be alien probes or their remains. While probes do land on Darwin IV in Alien Planet, and come to tragic ends, I think a scenario like that of 2001: A Space Odyssey is more probable. See: http://en.wikipedia.org/wiki/2001:_A_Space_Odyssey

There has been some serious interest in the search for alien artefacts on Earth,  and other planets and objects in the Solar System. So far as I am aware, there has been no credible claims of discoveries.

I found one scientific paper on-line that discussed the issue, but can't find it now. The paper concluded that the solar system had not been imaged in sufficient  detail yet to preclude the existence of alien probes.

Crash landing/ cast-a-ways

Could have the alien visit to Earth be unintentional? In this scenario, the alien visitors would have been forced to land on Earth and be unable to leave. The closest example in science fiction I could think of was the original Planet of the Apes movie. See:

http://en.wikipedia.org/wiki/Planet_of_the_Apes_(1968_film)

It is in this case that some of the claims of ancient astronaut believers might be true. Trapped on our planet, and bereft of their advanced technology, ancient astronauts may very well have resorted to helping the native human population to develop more advanced technology.

The plot of Planet of the Apes does not follow this direction though. The astronauts are barely able to survive, much less become like gods to the indigenous beings. Edgar Rice Burroughs' John Carter stories have a more optimistic, albeit unrealistic, outcome. http://en.wikipedia.org/wiki/John_Carter_of_Mars

Unambiguous evidence of this scenario would be difficult to find. If there was a crash, there would be no direct evidence beyond the immediate site of the crash, which could be quite small in extent. Any other evidence would be more easily attributed to more prosaic explanations.

So where do we stand now?

I have identified some lines of evidence that might provide proof of alien visitation. By no means do I feel that I have covered the whole range of possibilities. There are still questions I raised in my previous blog post that I would like to address.

I haven't actively looked for any of the evidence that could provide proof of alien visitation. Indeed, much of the search is beyond my ability and resources. For now I will limit myself to consideration of the possibilities.

Some of this speculation could be the basis for some interesting science fiction tales.

If There Really Were Ancient Astronauts, What Kind of Evidence Would We Find?

Now that I have finished my movie "Summer's Too Short" https://www.youtube.com/watch?v=Mk4tVFfgSP4, it is time to embark on a new project.

For many years I had an interest in the ancient astronaut hypothesis. Unfortunately, I have not found the kind of credible discussion that I want to see. I will try to start on that path myself and see where it takes me.

When I first heard of the ancient astronaut hypothesis, over 40 years ago, I was immediately fascinated. At first I was firmly convinced. But as I dug into the "evidence", it just dissipated in a puff a smoke. Nevertheless, I was still fascinated with the idea, albeit, disappointed there didn't appear to be any real evidence.

I think it is plausible that aliens visited Earth in the past. I  looked for people who have done a serious investigation, but only found vague comments about some speculation by Carl Sagan. That left me unsatisfied.

If there really were ancient astronauts, what kind of evidence would we find?

I have not seen any evidence that would convince me that the ancient astronaut hypothesis is valid. Old stone monuments can be easily explained by the skills people in the past could draw on. I am also uncomfortable with the implied racism inherent in some of the evidence.

I need to decide what kind of evidence would convince me. This is not a simple question.

Before we can speculate, we need to explore some other questions.

Where are they from and what is the level of their technology?

This could be two questions, but I think they need to be linked. The further away they come from, the higher their level of technology would be need to be. The more advanced their technology is, the harder it would be for us to recognize it. Their level of technology would affect how many of them there were and if they sent robot probes instead of living beings.

Why did they come here?

If they came here for scientific study, the evidence would be much different than if they came for colonization. Would Earth have been their primary goal, or might it be a way point on their route to their final goal.

Were they successful?

This is related to why they came. If they accomplished what they came here for, the evidence would be different than if they had failed. Between full success and abject failure there is a wide range of out comes.

When did they come?

Aliens who visited Earth billions of years ago would be much harder to detect than aliens who visited after human civilization arose. A closely related question would be how long did they stay. Did they ever leave?

How did they interact with humans?

If aliens visited openly, then evidence could be found in the cultural materials of ancient societies. If they visited clandestinely, we would need to look elsewhere. They might have engaged directly with humans or may have simply ignored them.

I suspect that there are many more questions that could be asked. For now though, I will cogitate on these as fodder for future blog posts.

"Summer's Too Short" Now On-line

After more than a year in the making, my new short movie, "Summer's Too Short" is now on YouTube: https://www.youtube.com/watch?v=Mk4tVFfgSP4

I began work on "Summer's Too Short" on March 12, 2014. I took a single photo of my garden every day until December 9, 2014. Over the last month I have compiled these photos into a short movie.

I did a couple of posts on my blog about the movie:

<i>“Summer’s Too Short”</i> Should be Done Shortly http://dynamiclethargyfilms.ca/summers-too-short-should-be-done-shortly/

and

"Summer's Too Short" Should be Done Shortly

I made good progress on "Summer's Too Short" this week. I think I have most of the work out of the way, so I just have some tidy up work to do.

I finished aligning all of the images. That is slow work.

When I took the picture, I tried to always use about the same position. Unfortunately, even slight shifts in position distort the image a little. I think I could use a image distortion tool in Premiere Pro to improve the match. That would add a lot of time, so I decided to stick to shifting up or down, left or right, or by rotation. That still left some mismatch, but I don't think it is a big problem.

When I watched the video, I thought I could see a couple of images that are still out of alignment. I will look into that more next week.

I tried to take the pictures at about the same time of day, but never got that exactly right. The colour tone varied from day to day as well. Some of the images are very blue. I may see if I can do some colour correction to reduce that variability.

I developed a sound track to the movie. I had a pretty good idea what I wanted; a sort of Doppler shift sound effect. I felt it would catch the sense of the rapid passage of summer. I tried to create the sound from scratch in Audacity, but wasn't happy with what I produced. Instead, I found a short clip of a jet fly past at http://www.freesfx.co.uk/. It was a little too short, so I stretched it out a bit in Audacity. I altered the pitch to compensate.

I produced a preliminary video with the images, titles and sound track. I think it looks pretty good. Not that I'm biased or anything. I want to leave it for a few days, then have another go at it. If all goes well, I should have it on-line by the end of the week.

Website Infection Removed

I didn't get far on my projects this week. My wife's health, of course takes precedence over all other things. Besides that, I had to deal with a malware infection on my website.

Website

My website got infected with malware last week.

Nick Wernick, whom I know through my involvement with the Society for the Study of Egyptian Antiquities, warned me that WordPress had a bug that scammers had started to exploit. Unfortunately, my site had already been compromised.

The company who hosts my site, Netfirms, had detected the malware and shut down my site. I wasn't sure at first what I had to do, but their support team was helpful. All the same, it took me a couple days to get the site back up.

They do offer a service that protects your website from such attacks, but it is quite expensive. The mid level protection is about the same as I pay for hosting, while the top level is more than five times as much. The low level protection is cheaper, so I may go for that.

"Summer is Too Short"

I had hoped to work on "Summer is Too Short" this week, but didn't manage to get anything done. I did open up the Premiere Pro file and did a little fiddling around, but no real work. Hopefully I'll do better next week.

A Little Work on a "Short" Project

I started to work on "Summer is Too Short" this week. My editing went well and I am hopeful I will get this done soon.

I shot "Summer is Too Short"  last year, but hadn't cut it together yet. It is a time lapse movie. I shot one image a day for about 9 months, which gave me about 280 images.

I didn't have a time lapse video camera, so I used a still camera. About a third of the way through, my still camera stopped working. I borrowed my wife's camera for the rest of the movie.

I hand held the camera, so the images jump around quite a lot. I expected this, but since I had to deal with a similar problem with "Contingency" (https://www.youtube.com/watch?v=79sPbUoD9zM), I felt confident that I could work around it.

I use Premiere Pro to edit the movie. I imported all the images and added them to a time line. The process I followed to line up the images was to over lay one image on either the previous or following image. I made the top image semi transparent. I used the motion controls to get the images to line up.

The adjustments were rather tricky, but I got better at it as I did more. I found it more difficult to deal with images that were at a different angle. Again, I have gotten better at  that kind of adjustment.

I am about half way through aligning the images, so I think I'll have that done next week. However, some of the images will need some colour or brightness adjustments once I have them aligned.
