Why do we find sea fossils around the world in inland places and on mountains?
Plate tectonics maybe? For instance, the entire Great Basin was once a shallow inland sea, the evidence of which is found in limestone deposits throughout the region. Uplift of the crust over millions of years and at the speed that your nails grow has given us the current geology. There is no evidence of a global flood anywhere. You find the fossils segregated into separate sedimentary layers according to their age. You’ll never find a trilobite and a whale fossil in the same layer of sediment.
Are you not familiar with plate tectonics?
Plate tectonics. Mount Everest is topped with marine limestone that was thrust up when the Indian Plate collided with the Asian Plate.
Please read a geology book. I think you would truly enjoy it.
