Those that think they are seeing "Jesus" or take a trip to "Hell" and back are generally suffering from serious delusions/hallucinations. Make them give proof, photo, vid, YouTube upload, live stream, something, anything. Hard evidence. They can't, so that answers your question.
I knew a guy who said he saw "Jesus" near his horse stables. I asked him for a photo or vid, but evidently "Jesus" had "bigger fish" to fry, couldn't stick around long enough for the photo op, which surely could have changed the current world situation, hopefully for the better. And "Jesus" never came back to visit the guy again. That's not nice.
Neuroscientists say that "tunnel of light" folks see at death is basically the brain's "electrical" shutting down, "unplugging" itself, so there's a flash of sorts, likje a camera flash, like unplugging a cord from a socket and you get that quick blue flash. The brain has alot of "electricity" running thru it, apparently.
But let's say "Jesus" actually exists. So what? He didn't do crap to change the oppressive master/slave society when he was there and has done ZERO to effect any change whatsoever in capitalist/imperialist violence, oppression on the earth today or EVER. And he doesn't save anyone from random accidents, disease, or violence, or war, or natural disasters. "He" and his "Father in Heaven" are woefully inadequate at helping the oppressed in the world. Well, they don't exist. Marx, Lenin, Mao, Castro, Guevara were far, FAR more important and influential human beings in the world effecting betterment for humankind than Dead Jesus.
