I have often said that if oil was from organic matter only, then why do we find it as much as 20 miles deep? Oil is everywhere, on land and the oceans. It is almost always found in rock formations. The dead and dying organic stuff would have to make its way down 20 miles through solid rock?

Naaaah! We're still guessing.

...then why do we find it as much as 20 miles deep?

Do you have a reference to such? The deepest well I've heard of is only 12,000 meters. That's far short of 20 miles.
