Dmitry Chernyshev. (№ 333409)

I, as an atheist, I can easily imagine a situation in which I at once admit their mistake and say that I was wrong and God exists. For example: flying with angel on clouds, life after death, visit to hell or heaven, talking to God, etc., etc.
I have a question for believers - if you can imagine such a situation, experiment or argument, after which you will immediately recognize that you were wrong and that in fact there is no God?
