The breaking down of bio-mass over millions of years into crude oil. Is what science has been claiming since old earth and evolution hit the scene. But was this claim ever tested? Was the conditions ever duplicated that the oil was found in to see of the break down process really took that long?

No, it never was.

So the claim that this happened was soley based on:

1) Needing evidence to support old earth, which would give the time-line for how evolution could work. Showing that life existed on earth 100s millions of years ago.

2) Needing evidence for a non-God based origins of life. One where it could never be questioned because "time" would always be the excuse for all evidence or processes that cannot be observed. Claims can be made, and when the process is asked about. The excuse that it takes to much time can be used so that this process is "never" seen. And the excuse can never be questioned.

Example:
Question: Where is the observable process for millions of years of claimed evolution?
Answer: It takes to much time to observe.
Question: Where is the observable process for millions of years of claimed break down of bio-mass to make oil?
Answer: It takes to much time to observe.

So time becomes the old earthers and evolutionists excuse for all unobservable processes.

But what if one process claim has been clearly debunked?
