re: Astrophysicist Dr. Willie Soon explains the abiotic origins of hydrocarbons.

It’s worth discussion but carbon (hydrocarbons) are present throughout the universe. It doesn’t mean that it has to come from an organic source like dinosaurs and plants. I mean how did the dinosaurs and plants get it to begin with?
We are all small parts of the universe. The matter that we are made of will eventually return there.
