Sader, if this place is a hologram, as physics is strongly suggesting might be the case, heaven could be one of the least strange eventualities post death.
There is every possibility that you're a video game character bud.
Question is, who is pushing buttons and why? Just some fun? A test? A better reality than the one where the real you currently is? Simulation for simulation sake?
Following the science doesn't take you to less strange outcomes my guy. Myths, fairytales, lies...physics is pointing us in exponentially stranger directions.
While it may not be the case for everyone, I think people are generally fearful of speculating as to the nature of existence.
It's just easier to believe that we're the product of the big bang and that it was a random event with no intent behind it. The moment one compensates for intent, you have to make too many adjustments to your world view and I really believe that most people are frightened of that headspace.
