A lot of folks must've missed that school day they talked about mathmatics in ancient history... Guess the archimedian screw must've fallen off one of the space ships...
Egypt-shmeedgypt.
Much more sophisticated, well engineered, better masonry, etc. pyrmids were built in the Americas by the Aztecs and Mayans. And of course people can't believe human intelligence was behind those either...
imo, Terrence McKenna still has the only salient theory on alien intelligence space colonization by mushroom spores which are in fact capable of traveling through space and successfully re-entering an atmosphere... as he once said:
"As I understand the Crick theory of panspermia, it's a theory of how life spread through the universe. What I was suggesting -- and I don't believe it as strongly as you imply -- is that intelligence, not life, but intelligence may have come here in this spore-bearing life form. This is a more radical version of the panspermia theory of Crick and Ponampurama. In fact I think that theory will probably be vindicated. I think in a hundred years if people do biology they will think it quite silly that people once thought that spores could not be blown from one star system to another by cosmic radiation pressure. As far as the role of the psilocybin mushroom, or its relationship to us and to intelligence, this is something that we need to consider."
From a wiki on panspermia:
"Spores are another potential vector for transporting life through inhospitable and inimical environments, such as the depths of interstellar space.[31][32] Spores are produced as part of the normal life cycle of many plants, algae, fungi and some protozoans, and some bacteria produce endospores or cysts during times of stress. These structures may be highly resilient to ultraviolet and gamma radiation, desiccation, lysozyme, temperature, starvation and chemical disinfectants, while metabolically inactive. Spores germinate when favourable conditions are restored after exposure to conditions fatal to the parent organism. According to astrophysicist Dr. Steinn Sigurdsson, "There are viable bacterial spores that have been found that are 40 million years old on Earth - and we know they're very hardened to radiation."
Every time one of those so-called Ph.D (pile it higher and deeper) scientists on those shows says "We don't know but it's possible..." I want to throw a brick at the tv.
