-- There is no 'question' whatsoever that methane is formed throughout the solar system by heat & pressure.
-- After all, 'Gas Giant' planets do exist.

Thus the only question remaining is: -- why is that fact ignored when we discuss the formation of hydrocarbons on earth?

Thats easy. To many PhD's dissertations and published research backed up the existing theory to allow it to be questioned even when we later learned about the composition of the gas giants.

Scientists, and scientist groupies, insist this sort of thing never happens. They get really honked off when folks suggest it does.
