Except that (if that’s true) humans don’t have any physical similarities with grass. At all. But we humans do fit all the criteria of a primate in appearance alone, like apes do.
…You know, fun fact. When my younger sister was in elementary school, she recalled an event where she asked her (obviously fundie) teacher “but then aren’t humans animals too?”. The c*nt of a teacher (and that school had a lot of them, I would know) yelled at my sister and humiliated her, saying stuff like “oh, do we eat and drink out of bowls then?”
That’s what one’s brain on fundieism does, people. And to this day I still wish I could find that teacher and punch her in her smug face.
EDIT: also, in my class, a teacher once told us the Christian creation myth as if it were a fact (while creationism isn’t allowed here), and when a classmate of mine asked her “where do the dinosaurs come in then?” she condescendingly dismissed him saying something like “that’s prehistory, that doesn’t count”.
