Are you suggesting they are mimicking things they have seen? i.e. alien visitors. Or they themselves were spacemen? I would find the latter utterly
unbelievable.
You can't create mechanical machinery, rockets, and all the rest, without advanced industrial processes. It would require factories, and advanced
knowledge of plastics, metallurgy, physics, and so on. There would be obvious evidence of these sorts of advances. You are saying we can find their
structures, bones, tombs, weapons... but we can't find any of the technology?
While some feel our ancestors were far more advanced than we realize, I think they were perhaps somewhat more advanced, but not anything even close to
what others believe, but were also a lot more ingenious with their solutions to problems than we would have originally thought.
I also don't think it's them carving what they experienced. I think this is just a normal carving misinterpreted. If they really had that much
exposure to something so amazing that it made them carve it in stone, don't you think they would find dozens of not hundreds of references? Not one
or two? I do.
