I'm sorry to say it, but religions are cults, and there is no god.
This sort of thing really should be obvious, but for some reason, people still believe in these sorts of things.
I guess the idea of a heaven is nice, but from my experiences, such a nice ending is quite unrealistic. It's too magical for reality. Reality is dark and horrible. It's painful and filled with nightmares, none of which make sense. Evolved beings that are covered with flesh and hair, inside of which hide pulsing organs filled with sludge and ooze don't go to heaven.
They rot. There is no god or afterlife. This universe is just too nightmarish to have such a thing. You can even ask.
I dare you to just blatantly ask loudly "God, if you exist, please give me a sign".
And then look for a sign that only a god could make. Don't fool yourself with a gentle breeze or a twig falling off a tree or something petty. If these beings are gods, it should be a lot more than just natural occurrences or weather or something mundane. Anything truly miraculous that would actually prove a god is just unrealistic. It won't happen, because that's just not what reality is like. It's sad, but true. Religions are tribal cults, and humans are evolved animals, doomed to die after living a meaningless life.
But these are just my opinions. If you disagree, please say so in the comments. Debate if you want. Get mad.
Passion is an interesting force.
