Earth’s plate tectonics would effectively have “erased” the traces of a civilization that lived billions of years ago.

He’s avoiding the bigger problem of explaining how these previous civilizations evolved taking into account what we know about our own evolution.
You’ve hit the nail on its head. There is zero evidence of ancient civilizations that predate the surviving old crust geology. Nonsensical article.
We know very little of where humans came from and can only speculate. I'd say it's possible, if they had existed, they likely did not originate here and were brought here or were simply developed here by a race so advanced, the ancients at the time saw them as supreme beings or Gods.
All this is odd because many of these same questions here can be asked about God. The fact remains we have no idea here God came from other than comments written by humans such as "God was always here, he is the end and the beginning" etc. And all that might be true, but still we have no documentary proof or hard evidence. I dunno. One thing I am fairly confident about is humans were not created on their own here simply because the chemistry/environment was right etc. I don't buy that.
