Let me tell you why this is controversial.
If i had said i'm convinced that quarks do not exist, you would have pointed me to the concrete reasons why physicists believe quarks to be a real thing.
Instead i said i'm convinced that God does not exist, and you're trying to get me to agree that on some unspecified worldviews there are unspecified reasons to take God's existence as fact.
That's a completely different approach, and i would say not very fruitful.
