Surprised so few are pushing back against some of the claims in this article.

Eg that the entire surface of the earth gets replaced in a million years by tectonics.

Many of the large plates are more than 1000km across, they’d need to be moving meters per year for that to happen. In reality it’s cm per year. Also typically it’s oceanic plates that get subducted and take material under the crust, not continental plates. If it were true, then how do we see dinosaur fossils, and creatures even older than that; how do we find rocks that are over a billion years old.

This doesnt reject the possibility that there was a civilization tens of millions of years ago, but it makes the article hard to take seriously. If you’re gonna spend time writing an article on this you might as well try to research it a bit more. Someone is gonna read this and repeat this nonsense like it’s some fun trivia.

A plate moving one centimeter per year would move over 10,000 km (6000 miles) over a million year, isn't?

It's two times the distance from New-York to San Francisco, one fourth of the Earth circumference!

And the Cretaceous–Paleogene extinction event was approximately 66 mya.

No, 10,000 km is 10e6 meters, or 1e9 cm, so at 1cm/year it would take a billion years, not a million.
