A compiled and very simplified version of convos I’ve seen and a convo I’ve been in. (To note, my responses actually weren’t directed at an opponent of evolution but a supporter who kept saying I was a creationist. Long story.)
Random person (RP): Scientists say humans come from monkeys. How can that be if we see monkeys every day at the zoo?
Intp: *mumbles under breath* Zoo? I see one right in front of me.
Intp: I said ancestors are not our cousins.
RP: What? What does that have to do with anything?
Intp: Look at it this way: my great-great-great grandmother is not my cousin. She gave birth to my great-great-great aunt who gave birth to cousins I don’t even consider part of my family. But DNA still proves their descendants and I are related. And that we’re related through our mutual great-great-great grandmother.
RP: Well, your grandmother isn’t a monkey.
Intp: No because in that explanation, my cousins are the monkeys and my grandmother is the common ancestor. What don’t you get?
RP: Humans can’t be compared to monkeys. Your grandmother was human back then and would be human if she were born today. Your cousins are still human. How can monkeys turn into humans? What don’t you get?
Intp: *mumbles under breath* That you survived so long on sniffing cat pee.
Intp: I said I don’t get anything. Sorry for bothering you.
