I never said an Atheist said that to me to begin with, but what they have said to me is "God doesn't exist". Hence, saying God doesn't exist, as far as I am concerned, is rejecting evidence found in nature, design, organization, etc, that he DOES exist.
I think it's clear that's what I was saying.
Which god created it though? There are hundreds of choices to choose from. Can't the same exact thing be proof that aliens created it too? Hell, you can use that as proof that the tooth fairy is our creator.
When we say proof we mean something that will pass the scientific litmus test. If whatever god was actually proven I would be an instant believer.
