The meaning of life?
It does not matter now that in a trillion trillion years nothing we do now will matter. (even in 10,000 years).
A life without god, knowing there's nothing after death, where uncertainty reigns...can be perfectly meaningful!
We're an insignificant part of the universe, haven't felt the time passing since it began, so why worry about what happens after we're gone?
It's the curiosity that matters, not what we find.
