Isn't possible to just accept God's existence on faith? As specofdust says: I indeed wonder why those who (supposedly) believe in God need to most prove His existence. Faith should be enough. After all, faith is what it is about. Remember? "For those who do not believe, no explanation is possible. For those who do, no explanation is necessary." Suppose that God, if He exists, has neatly arranged it that you can never prove or disprove His existence. Perhaps He did that for a reason. Perhaps He wanted people to believe in the principles He stands for, to follow them because you believe it is the right thing to do. No rewards, no promises. You do the right thing because you believe it is the right thing to do. Similarly, just because science has found a pretty plausible explanation for how we got to be (and please note, it never aimed to answer why), doesn't mean it challenges the existence of God. Religion has interpreted the debate that way. Science remains impartial on the subject. You may also argue that "man will never create an intelligent machine" but only one century ago, man would never fly or go to the moon... Sentience is an emergence phenomenon. If we ever get to replicate what goes on in the brain (not that hard really, we manage on a neuronal cluster scale already, so it is just a matter of scaling thigs up dramatically. Perhaps with the Pentium 5 ), we may well get sentience.
