Excellent point and one that I rarely read anywhere.
Back in the '70s I read Eric Von Daniken's book Chariots of the Gods in which he claims similar alien help in creating pre-Columbian civilization in Central and S.A.
Specifically he stated that the fortress of Sacsayhuaman, which was built on the ridge above Cusco, Peru at the height of the Incan empire, was constructed with the help of alien technology. It's stones were carved and fitted with such precision that a knife blade cannot be inserted between them. No mortar was involved. I went there and put my hands on that wall. Walked up and down it's length and I'm here to testify that it is a very clever human structure, not alien at all. The idea that aliens had anything to do with it is ridiculous.
In the city of St. Petersburg, Florida an inverted pyramid was constructed at the end of one of the city piers. Jutting out into Tampa Bay it is lit up at night and is an enchanting sight. It's inverted, upside down. It was built pointy side down and fat side up. If aliens helped to build the pyramids of Egypt, I think they might have done something like that to really demonstrate advanced construction technology. Alas, the desert structures were made by dumb humans only.
Chronological snobbery? Yup, that's us.
Does that have anything to do with the Biblical account I posted?
