Humans are not smart as we think. Our brain could never possibly understand what is exactly out there. The Earth looks flat, but you travel a bit outside and it looks round. The earth looks like the center of everything, but not really if you look from another point of view. Sounds like a double slit experiment to me.
I no not believe in afterlife, but I do believe it is entirely possible to be reborn again trillions, quazzilions years in the future and most likely in another "universe". Out consciousness would not be the same and it would not somehow be magically transferred to a new body. You would be a completely different person or animal without any knowledge of your "past lives" In my opinion living now is probably your zillionth life already billions and quazillion years in the future and it will continue ad anfinitum.
I guess in this life we could be grateful that some technological advances have been made to have our lives make a bit easier and suffer less.
