There was a reason that God said it was not good that man be alone. Man was without a mate, amongst animal creatures with mates.

once presented with his mate, he saw bone of HIS bone and flesh of HIS flesh. She was the only one LIKE him.

when SOME scientists bring up this malarky, they want to liken us to the animals, and that will open doors for the sick to come in with ideas like beastialty.... loving the created more than the creator
