Modern science is guided by the philosophy or methodology of naturalism. This means they either believe that, or go about their discipline acting as if God does not exist, or at least is not involved with the cosmos. As a result, most scientists deny that a designing intelligence is the cause of life on Earth. And yet the more scientists seek to find a naturalistic explanation for the origin of life on Earth, the more impossible it seems. Some have gone so far as to suggest that life must have been seeded on Earth by an alien civilization. This, of course, allows for the presence of a designing intelligence. To my amazement, Richard Dawkins holds this out as a scientific possibility. In the documentary, Expelled: No Intelligence Allowed, Ben Stein asked Richard Dawkins how life began. After admitting that scientists do not know, Dawkins held out the possibility that life on Earth was seeded by aliens, and considered this a scientific hypothesis. The exchange was as follows:

BEN STEIN: 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: Well, it could come about in the following way. It could be that at some earlier time, somewhere in the universe, a civilization evolved, probably by some kind of Darwinian means, probably to a very high level of technology, and designed a form of life that they seeded onto perhaps this planet. Now, um, 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 biochemistry, molecular biology, you might find a signature of some sort of designer.

Four things are of interest, here. First, when scientists have to resort to aliens to explain how life on Earth could have originated, you know they have no clue at all about the origin of life!

Secondly, Dawkins admits that design is empirically detectable. If that is true, then contrary to the anti-ID talking points, Intelligent Design is a genuine scientific theory.

Thirdly, this hypothesis—even if true—would not explain the origin of life in general, but only the origin of life on Earth. Alien life would go unexplained.

Fourthly, he is willing to countenance the possibility that a designing intelligence is responsible for life on Earth, so long as that designer is not a divine being. This reveals the fact that he not truly opposed to the existence of genuine design in biology, but simply prejudiced against the existence of a divine designer.

This says a lot.
