Quite right. Now, where does the Earth get these particular fossils, 100 miles underground where petroleum is ostensibly produced? Wouldn't most of the (non-biological) petroleum end up in completely different layers, or (more likely) associated with igneous rocks? How is it possible that paleontologists can help to locate oil deposits by looking at the types of fossils, if the fossils are very old, but the petroleum deposits are not?
Quite the amazing coincidence that basically all the oil on earth is found precisely where biological theories of the origin of oil say it will be found. :-)
Because those fossils are, indeed, as old as the deposits where they reside. I would like to know about such fossils and their relationship to the new oil in the replenishing sites.
