Lets start our owbn deep atheist forum religion, oddworldforumsinism!
Basically, what if nothing had a beginning, and nothing has an ending. The matter just keeps rotating throughout the spacial planes compressing to form new universi and countless new civilizations and species. We all don't have to have our own particular meaning, humans are just pawns when it comes to the BIGGER picture.
Maybe everything in the universe all has one big meaning. when you play a RTS, do the countless units have any particular meaning, it's achieving the big goal in the end, or no end. And humanity isn't at that point of universal meaning (yes, I know this sounds extremely bulshitty, but it's 5 in the morning here, okay)
