Is Evolution a science or a faith?

[Harris]

Gods? Ancient Aliens?

Can we please keep it "real"!
For a moment I thought I stumbled into the sci-fi channel.

Perhaps, he is pointing towards aliens in which Dawkins believe.
responding to a question:

“What do you think is the possibility that intelligent design might turn out to be the answer to some issues in genetics, or in evolution?”

Dawkins said, “Well, it could come about in the following way: it could be that at some earlier time, somewhere in the universe, a civilization evolved by probably some kind of Darwinian means to a very, very high level of technology, and designed a form of life that they seeded onto, perhaps, this planet. Now that is a possibility, and an intriguing possibility. And I suppose it's possible that you might find evidence for that if you look at the details of our chemistry, molecular biology, you might find a SIGNATURE OF SOME SORT OF DESIGNER, AND THAT DESIGNER COULD WELL BE A HIGHER INTELLIGENCE FROM ELSEWHERE IN THE UNIVERSE. But that higher intelligence would itself have had to come about by some explicable, or ultimately explicable, process. It could not have just jumped into existence spontaneously. That's the point.”
