I actually don't think religions have their own genuine value systems. They adopted already existing values simply to add legitimacy to their belief systems. There's a short play called "Kiss Hank's Ass" (or "Henryho prdel" in Czech), which illustrates this beautifully.

Religion basically says, "Believe, obey, don't ask questions, and you'll find salvation." Science, on the other hand, initially advocated precisely the opposite: "Challenge everything, falsify every hypothesis, and only assume a theory might be true after you've exhausted every possible way to disprove it, be skeptical."

However, science has mutated since then, becoming more dogmatic. You are viewed as insane if you attempt to disprove generally accepted theories. Belief is becoming more important than proof. Science is turning into a religion rather than its counterpoint.
