Anyone who makes the claim “there is no God” would be subject to the requirement of evidence to support such a claim. .
No, Because it is not a claim. It’s a disclaimer, because the default position is that is no sentient creator.
You are making that claim and it is up to you to provide the proof .
I’ll re-word the position for clarity. The claim “There cannot be a God or God does NOT exist” is not the same as “There is no evidence for God, or there is no reason to believe in God”
To say that there cannot be a God or it is a certainty that God does not exist, you would need to provide evidence for that. The lack of that evidence does not point towards its existence however as an un-falsifiable claim is a rather weak one than a strong one. I am saying that a God claim cannot be proven nor can it be disproved (tomorrow a God could simply pop into existence and submit itself for analysis and experimentation)
The atheist position does not burden itself with such requirements. It simply takes the position that there is no evidence for a God. One could take the next step to then say “therefore there is no reason to believe in a God” but I believe that step to be superfluous.
Atheists don’t need to make this any harder than it has to be and agnostics don’t need to shy away from the fact that they are essentially atheists too apprehensive to accept the label
