Something many atheists claim is that there is no evidence for god or religion. Not one single bit of evidence at all. But that's not true. It's frequently talked about as if it were an all or nothing kind of thing. As if all the evidence points one way or the other. But, it's possible for there to be evidence for something that's false.
There is evidence for god. It's weak evidence, and clearly overwhelmed by the evidence against, but it's still there. It's not nothing.
The biggest piece of evidence I can think of is that the vast majority of people believe in god. And this is not argumentum ad populum, but rather a probabilistic, Bayesian point of view. Which is more likely? The probability that so many people would believe in god given that god exists, or the probability that so many people would believe in god given that god doesn't exist? I think people are more likely to believe in something true rather than something false, especially if it interacts with them personally. Of course, people are willing to believe all sorts of crazy shit, so it's not much more likely. Which is why it's very weak evidence.
