Einstein believed in “Spinoza’s god”, which is essentially just nature and the laws that govern the universe. It’s not the same as believing in an anthropomorphic God and putting faith in scripture.

This is one of those reasons I always call myself an agnostic instead of atheist.

Those aren’t mutually exclusive terms. “Agnostic” answers whether you know a god exists, and “atheist” answers whether you believe a god exists.

I don’t know of any gods, and I don’t believe any exist, so I’m an agnostic atheist.
