you guys are a real disappointment, I'd expect you would at least review the material before making gross assumptions
if you had watched the videos you'd know that there are no putative scientific explanations for how ancient humans had advanced knowledge
of the solar system - no one asserts that humans were able to make these determinations with human sight and observation of the stars... no one...
they had no telescopes people - wake up!
I'll watch the videos. Can't now because I'm at work.
Until then, here's my generalization: If the Summerian texts accurately describe planets outside of our solar system, I'll be more convinced.
The Summerians might have had telescopes. Isn't glass an ancient technology? Maybe not wide-spread in ancient times, but still. Maybe I'm wrong. If they had glass, it wouldn't be a stretch to imagine some human figuring out that a piece of glass curved a certain way magnifies things that are close and that two pieces in combo lets him see things that are far away. If not with glass, what about with ice? Apparently, you can fashion a sphere of clear ice that will magnify sunlight enough to start a fire. A telescope with ice lenses might be impractical. The point is that telescopes are simple. I will believe in unfound telescopes before unfound aliens.
Now that I've made up my mind, who needs to see the videos? Just kidding.
It's possible that they did make telescopes, though no evidence has been found of this that I'm aware of.
Even if they did, it doesn't explain other ancient feats/technology.
A telescope that can see the color of Neptune and the axis of Uranus is powerful even by today's standards. Is it possible to make a glass telescope that is that powerful or accurate using ancient methods? Lense formation requires precision.
Did they destroy their telescopes and leave other technologies and amazing work behind?
