Biologists should not be the least bit reluctant to leave the useless theories of Neo-Darwinism behind or to abandon evolution by natural selection. To the contrary, we now have a growing body of scientific evidence that humanity is not, and never was, alone in the universe. And whoever, or whatever, the parties responsible may be, we know that they have at least a modicum of what appears to be beneficial interest in us, or they would not have manipulated our genes to enhance our cognition and self-awareness as they appear to have done.

On a philosophical note, I very much doubt it is a question of God or aliens. Because the answer, in all probability, will somehow involve both. We know that God works through men, even through the most unlikely of men. Logic therefore suggests that if aliens of any kind exist, God will work through them too.
