Cool info! This is one reason I believe there’s possibly life outside of our solar system. No matter how cold, hot & extreme we find life. From the 2 links below, scientists say some organisms breath rocks, some are called zombie life because they ebb back & forth from life & death & supposedly there’s more life 6 miles underground than humans above. One article that I was looking for but couldn’t find says if the Sun disappeared, went out today, life miles below the surface could live indefinitely. Amazing IMO.
