Well, regarding the story of creation in the Bible, it's not clear that humans come "first" even in Genesis 2, if we follow the story. Here's how it goes: God creates Adam, then Eve, then they have two children, Cain and Abel. Then Cain kills Abel. And then Cain says to God: "I will be a restless wanderer on the earth, and whoever finds me will kill me." And God responds: "Not so; anyone who kills Cain will suffer vengeance seven times over." And God "put a mark on Cain so that no one who found him would kill him." (Genesis 4, 14-15) But who are they? (whoever, anyone, no one) At this point in the story there should only be three people on earth: Adam, Eve and Cain. And in the following verse it says that "Cain made love to his wife". Where does she come from? One possible explanation is that the story of creation talks about one specific tribe, among other tribes that would pre-exist to the family of Adam, or at least co-exist. Which is kind of relevant to the debate of different species of humans.
