"If they can't reproduce it, how do they know?"

If you are really that curious you can go to a university and spend many years studying geology, or even better go read up on these scientific journals with the original articles and see how they came to their conclusions. If you disagree with how they obtained their conclusions you can write a scientific paper elucidating how they screwed up and why their hypothesis is incorrect. That is how science works. Just because you don't know why they believe what they believe doesn't make it necessarily wrong.

Why? All they can do is preach their pagan religion. They have no proof at all. Why waste all that time learning nothing but wild theories?
I'd rather go shopping.

In an ideal world, yes. In the messy real world with human ego in play, don't believe it for a minute.
