"Christianity, if false, is of no importance, and if true, of infinite importance. The only thing it cannot be is moderately important."

If it may assume the existence of spiritual beings, then, yes, it is.

It doesn't challenge even the question about such things. 

Atheism is the position people have that simply don't believe in a god or gods. That's it. 

Someone who doesn't believe in Gods can still believe in ghosts or other stuff. Not that I think it's rational. 

It´s not. The concept of the existence of spiritual beings, whatever name you gave to them,  is a religious concept.  If an atheist believes in the existence of ghosts or deities or anything like that, he´s not atheist at all.
