Yes, but as a scientist I see no reason to believe in some specific unprovable concept over any other. I find Christian believe as arbitrary as Muslim believe as arbitrary as anything else I can come up with. So how could I believe in any of them?
Yes, it is arbitrary. Believing that there is no creator to the universe is also arbitrary. That is because, science, as it currently stands, has nothing to say about the matter. Picking/not picking any religion is a matter of philosophy, not science.
Talking about creation is one thing, but these religions bring a whole host of other things into play as well that you cannot ignore.
There is no evidence for any of the rest of it, no evidence of interference by gods, no evidence of any real communications either. So saying you think the universe was created by [a conscious entity?] a god is entirely different than saying that you believe in a particular religion and all its narratives and usually inherent contradictions.
I agree that for many people belief in a particular religion can bring in a bunch of associated dogma that is at odds with science. My point is that it doesn't have to. Dismissing all religions just because some people do feel that way is throwing the baby out with the bathwater. Not every christian is a young earth creationist.
