And how do you know it forms slowly? Or should I ask how you know the "geological processes" are slow?
Here is the
link I posted earlier which explains some of the processes. Drilling for oil is what caused Glenn Morton and his compatriots to confront their young-earth beliefs, which were irreconcilable with the evidence they worked with every day.
Here is another article which outlines oil-forming processes. The question isn't whether oil can form quickly, but whether
all oil
did form quickly, and the obvious answer is no.
As I said earlier, my actual point was the sheer logistical impossibility of all the world's biomass and carboniferous rock -- check the numbers out again in my OP -- forming in the space of a few thousand years. The earth would have had to be overrun.
Anyhow, are you just saying there's too much carbon for a few thousand years to account for, or are you saying there's so much it requires millions, billions, or zillions of years to account for it?
You seem to think that carbon isn't a "concern" unless it's in the atmosphere. Well, how does it get there? You need to learn about the
carbon cycle. Organic matter in soil is oxidised by the atmosphere, so yes the numbers of living and dead creatures on earth do make a difference (considering all those that ever lived existed all at once according to YECs, and in such numbers to produce the entire world's store of biomass and carboniferous rock -- by the way, that's just what exists now -- it excludes what has been eroded and subducted under the earth's crust over millions of years). Respiration from those same organisms in the biosphere also contributes to the carbon in the atmosphere. Check the numbers, they're pretty big.
