Simple conclusion to this arguement
It is impossible to prove a negative.
This means that you cannot disprove something- it is impossible to do so.
One cannot say "unicorns exist" because there is no proof that they do not exist, that is futile.
So, until conclusive evidence of a magical man flying through the sky (who created himself, somehow, and also created robbers, murderers, and sinners) is found, there is no god. Guilty until proven innocent analogy.
It's impossible to prove a negative means you can't claim a negative either.
