> We don't know why we experience things. It's bizarre that we do. Nothing in our understanding of the universe gives any indication that a bunch of atoms thrown together by cosmological processes and then assembled into self-replicating patterns by evolution should be able to experience what is happening to them.

From an epistemological perspective, this is gibberish. Just because we do not know the reason why something happens doesn't mean it doesn't happen nor is it stopped from happening.

The rest delves into solipsism which is an odd place to start from to prove the existence of an alternate lifeform. In solipsism, your own existence is suspect.
