Is there any evidence that the word “God” means anything at all? (Quora)

I was asked this in a Quora comments column, in my capacity as a former teacher of philosophy. In that same capacity, I tried to answer it. Please note, I always made it my policy to try to teach students how to think, not what to think. 

There is evidence that theists use the term to refer to something, even if they are not able fully to describe what that something is. 

There is evidence that atheists use the term to refer to something, even if they consider that something to be non-existent. 

 We all use words to describe things of which we have no direct perceptual experience. Included amongst these are things that we do believe to exist and things that we do not believe to exist. For example, I have no direct experience of albatrosses, but I have no reason to suppose that people who claim such experience are lying. I also have no direct experience of wyverns, and yet I doubt the testimony of those who have claimed such experience, even though I am unable to prove the non-existence of wyverns. 

This is probably accounted for simply by my having been brought up in a “civilised” society disposed to accept the former but not the latter. My understanding is conditioned by my upbringing. Likewise, my education has enabled me to understand technicalities in my field which are deeper than common understanding, and that is why I considered myself able to teach. In other fields, I have no understanding beyond the fact that people who claim to know say that something exists. I choose to believe them or not based on a predisposition which is just part of my way of looking at things, nothing more. 

 In other words, the word ‘god’ has a meaning, just as the word ‘wyvern’ has a meaning. Both mean different things to different people, and some people will believe the word does not refer to an extant being while others will believe that it does, but there is sufficient mutual understanding of the thing referred to that we can use the word to communicate with each other.
