That statement has to be the most close minded phrase I've heard in a while. To think we are the only life in the universe? Come on why don't you TRY to use that gray matter in-between your ears.
You don't get out much.
It isn't any more close-minded than "God doesn't exist," which might as well be tattooed on the foreheads of the many, many atheists who clog up FR with mounds of mouldering mind manure each meandering minute.
We are the center of the universe, incidentally. We are also the edge of it. There is no privileged place spatially in the universe.
The astonishing conditions that must necessarily coalesce in in this particular planet, this particular solar system, this particular galaxy, and this particular universe to allow for mankind to exist at all makes our existence very, very, very special indeed. The odds against such conditions arising randomly are so prohibitive as to be essentially infinite. The time required to allow such odds to play out exceed the approximate 15 billion year age of the universe by many, many orders of magnitude.
It is our uniqueness that really troubles the atheists. It's what fuels their obsession to look for life elsewhere--to eagerly embrace and employ intelligent design strategies in the SETI context that they hypocritically ridicule and call phoney science when believers embrace and employ it. The Christian biblical account implies our uniqueness. It makes the astonishing claim that the Creator of the universe Himself manifested His presence in the flesh in this place at this time to offer mankind a more magnificent life and a permanant consciousness such as HE enjoys.
No, the biblical account doesn't necessarily say or imply that God has not allowed life to arise elsewhere. But God-haters and atheists would be greatly relieved to discern intelligent outside our solar system. They believe it would further undermine the special claims of Christianity--and that is very important to them.
For if the special claims of Christianity are true, all men--including atheists--are accountable to God for the lives and bodies that God created. The self-worshipping have no desire to face that judgment.
