The universe is old enough, and conditions sufficient throughout, for intelligent life to have evolved repeatedly over billions of years. This would be true of any universe that had conditions sufficient for intelligent life to have evolved in.
Since there does not appear to be an upper limit to intelligence, then given enough time, and perhaps with the help of genetic manipulation and artificial intelligence, intelligence would learn to imprint consciousness within simulated universes of their design. They may even learn to make ‘real’ universes - manipulating forces within their own universe to inflate space-time into entirely new ones.
Makers of universes - perhaps even our own.
But if it turns out it is easier for ‘god’ to code for an entire universe, than to physically create one, then statically speaking, it is more likely our universe is someone else's simulation. And if that is true, then the likelihood of existence after ‘death’ is good.
Wouldn't a programmer be morally obligated to continue sentient life imprinted within its ‘circuits’? And if not, wouldn't it at least be easier than starting all over again?
