No it doesn't, at least not before there has been the opportunity to examine the evidence. Science is not about accepting stuff in an uncritical manner. I should also point out to you that science is not about objectively/effectively "proving" anything. Those who fear science's quite proper potential role in investigating God's existence frequently misrepresent science in this way in an apparent attempt to show that God must be outside its remit. When human beings claim the existence of something, then human methods - science, in other words - are the proper way to investigate it, no matter what it is. And that means seeking evidence.
