Well let me give you a better example of what religion does. Let's make a more accurate parallel. God says homeopathy is true (prayers will be answered blah blah blah) I can test this empirically. The prayer hypothesis fails. This doesn't say much to God's existence, but it can be interpreted as to whether the claims that God does _____ is true, and it's found to be untenable. We can do this for MANY things. What we're doing, and what the entire debate came down to, is what God is. Does he exist as an entity/agent or does he not. The evidence shows that of the many attributions of his agency, they fail. If God exists, it's not the agent he's made out to be. People then use magic to explain away why the evidence doesn't support the God hypothesis but once you use magic, you're admitting failure because magic means that your side knows just as little to nothing as the side you're claiming magic prevents them from knowing. Using magic is admitting failure.
Another portion of the debate and my personal favorite focuses on the afterlife. The afterlife is nonsense because again it invokes magic, which people are captivated by. Everyone says "We don't know if there's an afterlife" but that's not putting either on an even balance either. Here's what I do know. If I ripped out pieces of your brain, your subjectivity is lost (I even have this in my signature) and what makes you "you" goes away. Death is the ultimate loss of brain function; there cannot possibly be any more loss than at death. So the expectancy to have brain function such as consciousness after death is nonsensical. If there's an afterlife, it won't include you as the brain. If there's a soul, it doesn't give a damn who you are. The only alternative is that there is a parallel thing that is sympathetic to your brain and lives on after your brain dies which again can only be made to exist through magic.
These were two strong points in the debate that the opposition could ONLY try to fight by invoking either magic or handwaving to try and reduce the playing field by "going nuclear" to lie and say science is a belief system (it is not, especially not the belief system like religion so the attempt to equate them is transparent and wrong) or to try and say " because science says it doesn't know, how can we accept that" where again, it is far more genuine to say "we don't know" usings truths than to say "we know" using lies.
