Not really. I don't claim to have proof that there is no god. I merely assert that not existing is the default state in the face of evidence-less existence claims. There could be a god, but that possibility has no bearing on how I live my life. If you want to ascribe a set of beliefs to me, the closest might be secular humanism.

Perhaps you might consider yourself to be agnostic?

Would you call yourself agnostic simply because you didn't believe Russel's teapot existed?

No, because that doesn't make sense.
