Fossil fuels without fossils

Elon Musk:

Once you start getting into deep methane or deep natural gas you’re actually tapping into things that are not related to dinosaur fossils. Methane is a naturally occurring gas. There are places in the solar system where the atmosphere is primarily methane. So it does not require organic origin. So if we dig too deep for methane, we’re actually going to a level that has never been seen before. Not even in the very earliest history of earth. So that’s very dangerous, I think.
