Are we all atheists?

William Lane Craig offers a good response.

No, we’re not atheists.  We believe in a God.

atheism:  disbelief or lack of belief in the existence of God or gods.

We simply don’t believe in other gods.  For gods, such as Thor, Ra, and others we find no compelling evidence.  I don’t believe in Thor for the same reasons I don’t believe in Allah or Vishnu.
