As one who accepts ID I would drop this from your argument. How could we possibly know that there is no other life out there? My theory of ID would imply that life is a natural part of Gods design.
Given the vastness of the universe there would mathematically be countless other planets capable of supporting life. If life is a natural occurrence according to Gods design then it would follow the same physical laws as everything else.
Where is the other life? And whose money am I supposed to spend, so that people can travel the galaxies to find out?
Not to pile on you, not at all, but I don't really care what life is on other planets. I have a hard enough time dealing with life on this planet. For those who devote their life to finding life on other worlds, more power to them. I just don't have time for it in my life. Let them try, and when they find something, if they find something, then I will gladly tell them congrats, and visit their multimillion dollar estate (or watch it on tv).
Till then, no.
