"Hi, yes, well spotted on the comparison between the snakes on the Malta plate and those at Gobekli Tepe."
Thanks Michael Seabrook.
The head of the cobra is flat – while this carving from Gobekli Tepe shows a bowl shaped head.
I expect, whoever carved the images at Gobekli Tepe and the Mal’ta Plate were more preoccupied with reproduction than they were with snakes.
We have many examples of advanced ancient technology (The Osirion – Unfinished Obelisk Aswan etc.). These, and many other examples of advanced ancient technology not only exceed the capability of the Denisovans – it exceeds modern day human technology.
So given you seem to acknowledge that earth may experience the transition of other cosmic life forms – why even bother trying to explain our past in terms of the three geographical dimensions and one of time?
A credible explanation of our past, that is confined to the three geographical dimensions and a single forward arrow of time, is not possible.
