A Question From Atheists

[Gawdzilla Sama]

Hello everyone,

I'm trying to understand the Atheist's point of view and I came across a question, I'd be grateful if you guys help me figure it out.

As you know there are many different gods in various cultures and religions which are significantly varied. The term "God" does not refer to a specific entity. So when you guys say "I don't believe in God" which god(s) are you referring to? What is the definition of that god which does not exist? There are certain gods that clearly do exist . Like the Pantheist's god which is the universe itself, so I assume you are referring to a "certain group of gods" I'd like to know what defines that certain group?  

Thanks for reading and sorry for any mistakes or inaccuracies in my use of the English language. 

Cheers.

I don't believe in the concept of "god". I really don't find magic interesting.
