English physicist, Paul Davies, says he is on the fast dial for SETI. He said that if there were any contact with aliens he would know about it. And as far as he knows, there has been no contact. Astrophysicist Hugh Ross says that the conditions necessary for life appearing anywhere in the universe are in the realm of impossibility. It is a miracle that there is life here. The book The Privileged Planet also discusses this. So, the push for the belief there are UFOs has to be from another source, and not from the existence of aliens, other than the illegal variety.
