There's allot not mentioned, a ton in fact, in the book of Genesis that science has discovered about life around us and the structures of cells, protein, ect. But the discovery of those, imo, hasn't disproved a creator either. There has been nothing discovered about the human body that disproves a creator. The discovery of alien life forms, again imo, is so significant that I feel it would have been mentioned.
Nothing can disprove the existance of a creator. But by the account in the bible it seems made clear that everything was made for man and man was made in God's image. If aliens were proven to exist (complex intellegent types or single cell kinds) what reason could a Christian come up with for their existance? That man isn't really as important to God as the bible makes it seem? Did God just get bored with all of the empty lifeless planets so he sprinkled some life on them?
This is a hypothetical discussion but it does seem likely that there is some kind of life out there somewhere in the cosmos.
