Cannot disprove a negative, the onus is on the ones that claims a positive statement about a god. That's like me saying prove that invisible blue monkeys don't fly out of the exhaust of a car
That's why in religion its called faith and not fact
If you are an atheist you should be able to prove that there is no God.
Some people believe there is no God. It is an act of faith. You could call it faith-based pessimism.
Don't atheists make the positive statement: Belief in God is ill-considered. Don't they have to prove it?
Prove what? That there isn't something?
Argument from ignorance
Arguments similar to, "Belief in proposition X is justified because
you can't prove it's not true," are based on the premise that belief in something is justified until sufficient evidence refutes its existence (i.e.
argument from ignorance). In this case, the theist is asserting that belief in God is justified even without evidence. While this view may seem reasonable to those who already accept the existence of God, this approach to belief merely represents a form of
compartmentalization. If we were to broadly accept the general premise (i.e., "belief is warranted because you can't prove a negative"), we would be unable to develop any useful picture of
reality because every claim would be necessarily accepted as
true until it was disproved. This is a burden that is impossible to meet when dealing with
supernatural claims. The theist is compartmentalizing his or her supernatural beliefs and applying standards different from those applied to other beliefs. To put it more bluntly, a rational person does not seriously claim that
leprechauns or
unicorns must be assumed to exist because we have not
disproved their existence.
Tellingly, apologists typically apply this premise only to questions pertaining to
their particular religion — and not to questions pertaining to other religions. The
Christian who argues, "You can't prove God doesn't exist," would almost certainly reject such an argument from a
Hindu who says, "You can't prove
Vishnu doesn't exist!" This compartmentalization, in which one's cherished beliefs are subjected to a special set of standards, is a form of
special pleading.
