If we use the same assumptions that radiometric dating experts make: i.e.
For as time goes by, the oil should seep into tiny pores in the surrounding rock, and, over time, reduce the pressure. Perhaps because our oil deposits were created as a result of Noah's Flood only about 4600 years ago?
Some scientists say that after about 10,000 years little pressure should be left. Assuming that this rate has been constant in the past we can conclude that the earth would have been so hot only one million years ago that no life could have survived.
This results in a constant yearly increase in the distance between the Earth and Moon." "One cannot extrapolate the present 4 cm/year separation rate back into history.
It has that value today, but was more rapid in the past because of tidal effects.
All of the proposed theories as to where it came from have serious problems.
