Atheism -"No God, "religion has no validity"

[robvalue]

The most accepted definition of atheism is that you lack belief in gods. In other words, you see no good reason or evidence to believe they do exist. It doesn't mean you are necessarily saying that they actually don't exist. What that says about religion is really up to each atheist. It would be a safe bet that it would follow on from this to say most religions also lack evidence and are invalid, but it's not part of the definition as such. Atheism only directly assesses claims about existence of gods.

Atheism says nothing more than this, so no it's not claiming anything about where the universe came from or how. People tend to tack on stuff like this, but it's totally invalid. Any particular atheist could hold any number of further views, but that's nothing to do with atheism.

So unless you're saying you're a gnostic/strong atheist, who also claims there is no God, he is wrong. And either way, claims about origins are unrelated so that's a red herring.

Hope that's of some help?
