Several yeas ago I saw someone interviewing little Dicky Dawkins (Sorry, I just can't resist). The interviewer asked what was the origin of life here on Earth. Dawkins said it could very easily be space aliens. I waited for the next logical question of "Well how did life begin on the alien planet?" but the interviewer let a golden moment just slip away!

Precisely. But atheists aren’t concerned about that, its simply a matter of contempt for Christianity — specifically Christianity.
I remember asking my science teachers when we were learning about the Big Bang, “What banged and where did it come from?” they hemmed and hawed A LOT. (This was my idea of fun.)
