The true answer only lies ahead after we move on from this world. Which is extremely frustrating, because more than half of humanity is born into faith and firmly believes in the afterlife and the existence of God. Then this niche amount of humanity, which doesn't believe in the afterlife tends to challenge faith itself, brings it's own theory called evolution by claiming we evolved from monkeys. As a human i don't claim any theory to be steadfast, i wish to live my life as peacefully as possible, until it comes to an end. Beyond death, whether what happens, if i was good in this life, then God shall reward me. If there is no existence after life, then i shall rest in peace in my grave. Leaving all that is behind me. In both ways, you are actually looking forward to eternal bliss. Because for humans, sleep is truly the peace they are looking for.
