Also, you can’t prove there isn’t a God any more than theists can prove that there is one. So “this bickering is pointless.”
Well to be fair, the burden of proof lies on the person making the claim, not the one disputing it.
Therefore, when making a claim that God doesn’t exist, the burden of proof is on the one claiming God doesn’t exist.
Disputing the claims of someone else is not a claim in and of itself.
For instance, saying “string theory is true” is a claim. Saying “string theory isn’t true.” Is not a claim. At that point the person who believes string theory can present evidence. Only if the evidence is shown to be accurate evidence is the opposing side then tasked with providing evidence which shows string theory to be untrue.
So, as the ones opposing the theory that God exists, the atheists need not provide any justification for their non-belief until those who claim God does exist provide some empirical evidence.
This is how claims are tested in laboratories and court rooms.
