Life is complicated and contradictory enough while it's happening. Lots of moving parts and auxiliary subsystems all going on simultaneously. What makes us think that those complications and contradictions can finally be "solved" once all the parts stop moving? Sure, we can get "facts", but "facts" are always there to be had if you look hard enough. But "facts" are just a part of "truth", and perhaps the least determinant part at that. After the facts, conclusions are drawn, and that's where we believe what we want to believe about what it is we think we've found.
It is to laugh!
