There is no such thing as a religious scientist.

One of the fundamentals of science is Occam's Razor. It says that when there are many possible solutions to a problem, the one that adds the fewest new questions is probably correct.

This principle, unfortunately, pretty much means you can't believe in God.

See, we're looking for an answer to "Where did everything come from?" When we answer "God," though, we're adding a hell of a lot of new questions, including ones that are worse than the original. Including "How does this dude live forever?", "Where did he come from?", and, of course, "If there's an intelligent force behind the universe, how can pigeons exist?

Before grasping that theist belief system, then, the card-carrying scientist will research more plausible ones. Like maybe walruses created everything. Sure, they don't seem smart enough to create a platter of tasty brownies, but at least they're not invisible, and we know they exist. Or, Martha Stewart made everything. Now we have to deal with the question of how she's been around since the beginning of time, but hey, if anybody's actually capable of crafting on the atomic level, she's the one. I'm pretty sure she's got a microscopic hot-glue gun.

The only answer less plausible than God? Two invisible old men created everything.
