If we explain every mystery by crafting something, then our world would not advance. I tend to believe in god, i don't believe in hell, and in alliens. And the bible is not made up.It is either true, or : i have heard that a part of our brains actually can create a state of mind, where we are likely to see things like visions, but we don't know they are creations of our mind, so some people may think they have contacted with the god, but that is just imaginary, or the reason for activating that part of the brain is due to god intervantion
