That's not really a reason.
Neither can evolution.
but it dosnt matter if evolution is real or not lol even to atheists.
but disproving a god would destroy the life of a christian. they have nothing else to believe in. they depend so much on magic and luck. they cant imagine themselves in a world where they have responsibility for their outcome.
this is why religion fights advancement so hard.
disproving god isnt an atheist's goal.
making a world where we dont even NEED a god is how things improve for the best.
people of faith get very offended over it because they fear a world without god lol. because everyone else would be fine, while they would fall behind. they are seeing that world in front of them as is lol
