I'm a rather lately evolved metazoan with all my roots on this planet, as testified to by the way my DNA has traceable connections to every life form on Earth, with no genes from anywhere else. Every single living thing on this planet is related by blood to a common ancestor. There are no aliens in my woodpile.
