We found oil. We used it to power machines. If super advanced humans really did live in Atlantis, and they used up all the oil, there’d have been none left for us.

Sure, maybe they started out like us, used it up, and then moved on to better technology. Then for some reason they could have recreated it and put it all back.

Or maybe they skipped oil altogether and used some other power source that’s better for the environment.

Either way, if an advanced civilization really did predate us, the “leftover” oil would seem to say that there’s energy to be found elsewhere. Which means that even if we do run out of oil in the next few years, that doesn’t mean we’ll be out of energy.
