Why do you assume the mountains we see today were always there?
And oh yes I always love the use of the word “scientific” as a shut up word. Since I started noticing its use in this manner I think of it the same way a liberal use “racism”.
I don’t. The Himalayan mountains were seafloor before India slammed into the underbelly of Asia.
But that was a long, slow grinding and ongoing collision. It didn’t happen since 4004 BC.
