It doesn't matter what proof you have, they won't even entertain the notion that you might have a point, regardless how much they might disagree with it.
Not one of them will even contemplate looking for any evidence, even right under their noses that can contradict their faith.
This is due to spiritual reasons. Their minds are essentially bound and clouded by the spiritual enslavement that they subscribed themselves to. This will be reversed in time. Don't waste time or energy on people that are too far enslaved, but do look for people who are in the process of changing their ideas for the better.
