What if humans WERE animals? Like everyone is just some different kind of animal? but we all have the intelligence of a human somehow?

There is no "IF".  WE ARE is definite.

Humans are animals, genus apes.  Some humans here do not have the intelligence of a wood post.  We may classify ourselves to be smarter than other animals, but we are not.  Others do not have a problem eating you if it means survival and you died off first.  They would be planning their next meal.

Other animals CAN LIVE IN THE WILD. Can you? They can smell out what is edible and what plants are not to be eaten. Can you? What water is good to drink and what is bad water.  Can you?

Humans are animals.  We're all the same kind, "human."

We don't all have the intelligence of a human.  If you establish cut-off points, there are extraordinary individuals beyond those points at either end.

We just are animals.  I don't think your question is very clearly worded.  But there are otherkin of course.

And what if 1, 2, and 3 were numbers?  And what if you could buy a computer at a computer store?

humans are animals, so I'm unclear what you are asking....

What do you mean, "if?"
