Not at all. Science just doesn't deal with things like "spirit" and things outside of nature (the super-natural) because they can't be observed, measured, or tested. Science deals only with those things with which it's methods are capable of dealing. The spirit world isn't accessable to the techniques of science.

I agree with you there. However, why do so many people use science as an excuse not to believe in God, because He cannot be scientifically proven to exist?

For some people, it's because they're proverbially from Missouri: they have to be shown something to believe it.

For some, it's a convenient excuse.

And for some, it's because their religious teaching didn't deal with the question of the relationship between faith and reason.

I've never heard any atheist say: "I don't believe in God because of science." What I usually hear them say is something like: "I don't believe it because there's no evidence for such a belief." Or words to that effect. I'll let the athesists speak for themselves.
