Oh don’t be silly @Patrick. If Adam (and Eve) existed, the would be ancestors of us all, and it would be the same Adam for all of us. Depending on when he lived, he could have been a Sapien, Neanderthal, Erectus, Antecessor…or what ever. If he was recent, of course he would be Sapien.
This has nothing to do with who was outside the garden. If they were recent, the people outside the garden would have been Sapien with a dash of Neanderthal and Denisovans =).
