Carl Sagan talks about "the gods." This clip is from Carl Sagan's Cosmos episode 10, "The Edge of Forever."
The contrast here between the laws of nature and gods is very instructive. People might have legitimately different views on just what the laws of nature are and how they operate, but when you get right down to it no one denies that there are laws of nature and there is very little disagreement on what the basic laws of nature are.
People don’t deny the existence of gravity, for example. Why not? There is just too much that happens every day for which gravity is the most obvious and best explanation. It doesn’t make sense to say that we fall when we trip because invisible fairies push us, or a pencil falls when we drop it because invisible fairies are pushing on it — that if the fairies didn’t exist, we and our pencils would never hit the ground. Some common force is acting here on us and the pencils; gravity not only explains what happens, but allows us to predict future events with great accuracy. The fairy theory doesn’t.
