Please be clear. In contemporary science you supposedly cannot posit the existence of intelligence in the universe. It doesn't matter if your reasoning follows the same pattern of historical science used by Darwin, as, for example, in Meyer's Signature in the Cell. "No intelligence allowed," as the film Expelled made clear.
There is one exception. Just as he explained in the film Expelled, Richard Dawkins is prepared to believe in space aliens, the U.N. now wants to establish a liaison with these unknown creatures, even if there is no evidence for their existence at all--just speculation. A Malaysian astrophysicist is to be the first ambassador of the world to little green men on Mars, or wherever they turn out to be.
It is all put forth in complete seriousness.
