Scientists have discovered organisms that can live without oxygen. If you are curious to see them, you can rent a submarine and descend on the bottom of the Mediterranean Sea, to L’Atalante.
There, the salt concentration is so high that basically we can talk about a death lake under the sea. Well, it looks like it’s not very dead.
I am not interested about details regarding this life form, what is important is that we can more easily imagine life on planets without oxygen. With a few exceptions, researchers have studied the surface of planets from a distance, now they have serious reasons to try to study them in depth. They shouldn’t think that without oxygen there is no life.
Me, for example, based on the age of the planets, I start to think that inside them more advanced civilizations are developing, but not as polluting as we see in science fiction movies. Obviously, there are other planets with more primitive life forms, like the ones discovered under the Mediterranean Sea.
