If you can't be certain about the simplest of things, explain to me how you are certain that God is not real?
Right out of the gate, this post starts off with a burden of proof logical fallacy:
Burden of Proof Logical Fallacy(Sometimes referred to shifting the burden of proof)
Description: Making a claim that needs justification, then demanding that the opponent justifies the opposite of the claim.
This probably falls with the PRATT area (Point Refuted A Thousand Times).
But just to reiterate: the burden of proof lies with the individual making the claim. If someone posits the notion of a god, a demon, a leprechaun, a fairy, a pixie, bigfoot, yeti, little green men, or The Flying Spaghetti Monster, regardless of the thing being mentioned, it is up to the person positing the claim to back up their claim.
There is no burden of proof to the individuals asking for evidence or providing counter-evidence to the individual that started the claim. The burden of proof is with the claimant; not the individual's providing feedback on the claim.
