I Don’t Think I Believe in Infinity

In order for anything to be infinite, it would have to eventually exist in every incarnation of itself possible. This includes incarnations in which it is something it is not. So with infinite grains of sand, there would have to somewhere exist a grain of sand that is invisible. And one that is a house. And one that is a turtle with fifty-two heads. And one that is a turtle with fifty-three heads. And a grain of sand that is sad. There would be a grain of sand that is a human. And this particular grain of sand that is a human would have knowledge of the whole Universe and would have shared that knowledge with every living being inside it. Since this doesn’t seem to have happened, I don’t think I believe in infinity.
