*sigh* I now found myself in a sort of useless, pointless argument trying to argue that 2+2=4 while others are calling me closed-minded for not accepting the possibility that 2+2=7 or 3 or even 5.
First, GS and Iguana(to a lesser extent):- your ancient alien astronauts claims are absurd. They assume that ancient ruins such as walls or pyramids or whatever could not have been made by the indigenous humans of the past and had to be created by aliens. I suspect that the above members who subscribe to such theories have been watching too much science-fiction drivel such as the Stargate TV series, a series I mercifully avoided due to its Star-Trek-like sheer awfulness, and which featured notions of aliens having gotten the Ancient Egyptian pyramids built and similiar hogwash.
Basically, my point is that humans are not all that stupid and it is indeed easily likely for humans to have created the pyramids, or drawn the Nazca Lines or built Stonehenge or the walls of Greater Zimbabwe or the ruins on Easter Island etc. No need for aliens to have built those monuments. Mind you, there have been previous attempts to mock history. There were H Rider Haggard's notions re Greater Zimbabwe, almost as bad as the current extraterrestrial myth-claims:-

The Condon report, last I checked, made a fundamental conclusion that there was no possible genuine evidence to confirm the existence of extraterrestrials. Yes, there are always incidents for which no explanation can be given due to lack of evidence and so on, but what do you expect? We humans have not fully managed to scientifically analyse. I duly checked your Socorro mention. Err, it seems
that there was only one eye-witness to the whole incident. Now, given that there have been many attempts by fakers to generate false evidence to support UFO claims(re crop-circles etc.), having just one witness to the Socorro Incident does rather invalidate the point, rather:-
http://www.ufocasebook.com/Zamora.htmlThe COMETA report is not credible. It apparently claims that Easter Island artifacts were of extra terrestrial origin.
Last point:- if aliens are so advanced that they are able to cross vast interstellar distances , why, oh why, would they be interested in a puny, technologically backward civlisation such as ours? It makes no sense. It is the worst sort of hubris to assume that we humans are so important that highly advanced aliens would be interested in us. I mean, what on earth do we have to offer to such aliens? Nothing!
