The Genesis story needs to be modified to include something to this effect:
And God threw an asteroid at the Earth, hit it, killed the giant reptile species and began to create hominids. Over time, Homo sapiens sapiens became a dominant hominid.
Spiritually, incarnations into the Homo sapiens sapiens bodies began to happen. The Homo sapiens sapiens body was a good selection.
And God said, this could be good. Let's see how this develops.
