The wealth of things you see around you doesn't exist in nature. Stick figures doesn't exist in nature, things in nature doesn't have black outlines yet we draw that everywhere in cartoons etc. Human have proven we have imagined many entirely novel things that doesn't exist in nature. And the creatures I posted have many aspects to them that are entirely unnatural, you clearly know that there are no animals like that even without knowing about all animals, so clearly they are something novel and not just more of the same.

Anyway, whenever you put yourself in a position where you can say "nuh uh, to me that isn't like that!" to everything, you are just tricking yourself when you do so.
