The existence of accounts of those claiming to have seen miracles is not evidence that they were honest or correct. Plenty of other religions also feature claims of those who said they saw miracles done (e.g. Mohamed moving a mountain) - doesn't mean we should rush out and believe in those.

Or, for that matter, look at some of the crazy "fake news" in modern times - somebody starts a rumour in service to an agenda, and soon you've got a gunman holding up a pizzaria, thinking he's going to reveal to the world Hillary Clinton's pedophile dungeon in the backroom, which he has faith exists because somebody on the internet told him so.

Agnosticism is the sensible position. Maybe there is something greater, maybe not. But if there really is a God, and it indeed operates on the basis of sending everyone who doesn't choose to subscribe to 2000 year old rumours to hell as punishment for our skepticism, that's just power without goodness, and morally unworthy of worship anyway.
