The second set of two hours lost my attention, but Really enjoyed the first two hours.

I thought the Second two hours was too much, SO IT HAS TO BE ALIENS.

You can't claim archeologist are to stubborn to think your way, when you do not have solid proof yourself, and since there "cannot be any other explanation but aliens." There are thousands, if not millions of Science Fiction Novels where people just make up stuff. Jules Verne himself had radical idea at his time about space, and so close to accuracy at times, does that mean aliens visited him? because according to Erich it cannot be imagination, no it had to be REALITY! I can buy some of the stuff, honestly I can, (the artifacts of plane models was really interesting). but to call out others for not conforming to your thoughts is not very professional.

Also the plane artifacts I mean maybe they had an idea of flight, but maybe never got it to work? not that aliens gave them planes and took them back.
