XP,

From this link you provided:

https://old.reddit.com/r/conspiracy/comments/5o4gpy/the_abiogenic_origin_of_oil_the_fossil_fuel_myth/

It says both this:

Abiogenic hypotheses generally reject the supposition that certain molecules found within petroleum, known as biomarkers, are indicative of the biological origin of petroleum. They contend that these molecules mostly come from microbes feeding on petroleum in its upward migration through the crust,

...and then this:

Modern geologists think that commercially profitable deposits of abiotic petroleum could be found, but no current deposit has convincing evidence that it originated from abiotic sources

So.... abiotic oil exists, but the oil we have used to fuel industry is has not been abiotic.

Is that what you understand, too?
