Those who think the idea is ridiculous, there is nothing proving beyond of a shadow of a doubt where or what we come from.
I don't have a firm belief on what or where we came from.
I don't believe we appeared out of nothing. Until we can completely duplicate the process in controlled environment.
Possibilities - however humans originated can't be replicated here because it began in another planet or world with resources or technology that do not exist here
- we are in a computer simulation, the same as if we create a virtual universe with highly advanced AI, and lock them on a planet in that simulation with rules, resources, etc, and see what they do.
- were created here from some type of advanced life form that is gone, died, or hiding themselves
- came from another dimension, the other dimensional superstar turned black hole hypothesis
Thus far even though I don't think we came out of nothing, see no solid evidence either of any type of afterlife or future after we die, though I hope there will be one and that this isn't it.
