“There are literally oceans of oil deep underground, far below where life has EVER existed.
How do you explain THAT?
“
Especially since last time I checked, oil rises relative to surface water.
Perhaps you are not taking into account surface absorption and adsorption? Surface layer effects have enormous importance.
What examples of such oceans can you offer up?
For sake of discussion, assume an old Earth. Let's also assume a buildup of organic sediment at a rate of one sixteenth of an inch per year. Over a billion years, that would be 986 miles of accumulated sediment. This in part explains how microorganisms can be found so deep into the crust.
