Go check out the .pdf and see the petroglyphs yourself along side the high energy physics simulations and experiments. Also want to point out that the author sticks to the status quo date of 10,000 BC as the starting age of the petroglyphs but the way he wrote it gave the impression that they have far older ones. No one ever seems to admit publicly that humanity is older then we know, no one ever seems to go further back than 10,000 BC.
