There are no scientific reasons to believe in gods. None. In fact, science doesn't even investigate it, because it looks at things that can be observed and tested. God belief falls outside this realm. People may look for evidence of their god in science, but they will not be using the scientific method. They will simply look at facts that science has uncovered, and apply them in ways that fit with their belief. They will also look for this evidence in nature, in children, in charity, in art, in music, in genocide, abortion clinic bombs---and they will find evidence to confirm their beliefs. But they still will not be using the scientific method. And not using the scientific method means that they will always be under the influence of confirmation bias.
So while nothing prevents a beliver from looking at scientific evidence---or any other body of evidence----to confirm their beliefs, science still has nothing to do with confirming god belief. In fact, the most science would ever do to confirm a god is to try to falsify god's existence. That is how science works. But it cannot falsify god because it cannot observe a god or test it. It can only say it finds no evidence for a god.
As such, it seems silly to look for scientific evidence to support god belief. It's like wanting your cake and eating too (whatever that means). You want to believe without evidence---and yet you still want to validate it scientifically. This is impossible---because scientific evidence would actually negate belief, since belief is not needed for science. If you believe in a god, go ahead. Nothing will stop you. If you wish for science to validate that belief--well then you need more faith.
