So that fella was in Gabon 1.8 Billion Years Ago?
The 'fella' is a Nobel Prize-winning physicist and former head of the Atomic Energy Commission. The uranium deposits were independently analyzed by an entire team and were determined to have been extracted and utilized. Such uranium deposits have never otherwise been found to be naturally occurring. They were dated to be 1.8bn years old. That leaves two choices: 1) believe that the reactor was intelligently designed and operated during that time frame, or 2) believe it was a natural geophysical phenomenon.
I'm taking door number 1. But doing so makes Darwin's vision of human evolution impossible.
