In the end it all depends on your belief. I don't see any tangible evidence for the existence of any of histories endless parade of gods and first hand accounts of people who have died and came back (operating table) has conflicting information. Most people say nothing, some describe their particular ideas of what they believed the afterlife was going to be... of course one can make the argument that if you died on an operating table and was bruoght back that doctors are more powerful than god, like god was somehow tricked into thinking you were finally dead but those pesky doctors outfoxed him again. I don't know, that thought amuses me.
For me? I sincerely hope it's nothing. I want to die because I'd like to stop existing. Being sentient is what I want to escape, and living amongst fluffy clouds won't really fix that... if it could, I'd of trained to become an airline pilot. But I digress...
What comes after life? Almost certainly nothing. We're tiny fractions of star dust energy given life so that energy can experience itself and death is just the lost of ones current consciousness. Destined to dissolve back into the earth in one way or another, that energy gives new life to grass, plants, sea creatures, or feeds a flame, depending on how your body is handled post mortum. In that way, life continues even after your death, but your conscious self will be lost with the cessation of brain activity. It's impossible to understand what death is like because it's not simply a black void, it's a sudden and complete stop to your entire existence. It's the color of nothing. The taste of the color blue. The sound of a good nickelback song. It is incomprehensible.
That being said it's interesting to consider the possibility of a god or gods. Science tells us you can't have something from nothing. Matter can not create itself... so.. was the universe always here, or was it created? Can science explain that creation? If it was a god who created all things, who created that god. In a long enough time line, there was nothing and suddenly everything... unless of course everything just always existed. But that makes as much sense as a magical creature creating all things.
If there is a god, I don't believe it's one any of earths many religions has ever truly understood. I don't believe it to be full of hate, or full of love. I don't think it's so petty to punish anybody for an eternity for the deeds done over the course of their earthly life, but I don't believe it rewards either. Maybe when you die it lets you choose what kind of afterlife you want, if you want one at all. Or maybe it sends you to a concentration camp style hellish dimension where you're tasked with breaking rocks into smaller rocks for the rest of eternity. Or maybe it lets you sit on a beach of white sand and bright blue waves sipping coconut flavored alcoholic beverages while smoking weed, surrounded by buff guys and voluptuous women? Maybe it lets you become your own god, and you can create and shape a universe all your own, and decide the after life of your own people? Maybe you die and Orpheus is there with a red and blue pill, wanting you to join his resistance. Maybe the silver rain curtain of this world rolls back and all turns to silver glass before you see it, a far green country side under a swift sunrise.
My point is, we don't know. We can't know.
