High a top the Rockies at 8,000 feet, there are fossils of marine organisms, how is that possible?

The earth is an active man place, with mountains being thrown up by geological forces, and then eroded to their roots. If the land being thrown up started below the sea, then seashells are found high in the mountains.

It might. it might because if you think about if they discovered if we came from (lets say something funny like aliens) and thy found cells that matched and they would have t do more research about it but would most probably change their theory.
