The question of evil is perhaps the strongest line of evidence. I don't want to discuss it on this thread but will always be happy to debate it.
Evidence against a particular belief about God, perhaps. Not evidence against God. (we haven't had one of these debates in quite some time, actually)
There is also the evidence against many of the claims believers make for their deity.
Evidence against some people and their claims; not God.
Contrary to common religous claims..
We know he isn't needed to explain the design of the living world
You mean, like the 'how' of things? That is not in conflict with God.
We know he never performs miracles that defy rational explanation
Evidence? Because we don't know this. Unexplained things happen all the time.
(I agree with you, mind you... only because i know that we are limited as to what we consider a rational explanation... according to our current and limited understandings of what is real/possible/etc. So what some consider 'magic' or a 'miracle' does have a rational explanation; just one that we do not understand. If God has infinite more wisdom and understanding of what we have - as a creator of the universe(s) would, he would not be limited as we are)
No holy book shows any supernatural influence
No holy book, or no holy writing? There is no proof of such influence, I would concede.
But even if so, this is only evidence against God if God were dependent upon a book (or writing) being holy.
Nobody in the history of the world has ever uttered a word of prophecy that required supernatural inspiration
You don't know something this. You're assuming.
In short the evidence shows the concpet of god is redundant apart from its function as a place-holder for stuff we don't know yet.
All that works against is a god of the gaps. A particular concept/idea of God. Not everyone (not even the majority, I would posit) even believes in such a way.
