If we can replicate the natural process for making diamonds, why can't we make petroleum?

If you’re asking about man made fuels and oil, we can. It’s very expensive though. That’s why synthetic oil for your car is more pricey. Synthetic gasoline is so cost prohibitive right now that oil prices would have to be around $150-$200 a barrel for that it to be worth producing. Mother Nature did us a huge favor in creating petroleum in the earth.
