sorry but I disagree...
The purpose of being "alive" is to better ourselves and elevate ourselves. That way we can achieve greatness in this world and possibly (if u blv in religion) draw us closer to a higher source.
When the universe was created it was not necessary, God was complete...he did not need to "give"...but being godlike is being able to give selflessly...thats what separates ordinary man from godlike people...those that give are emulating God and thus drawing themselves closer...
I know its all a bit odd the answer, but being selfish is un-Godlike.
Being alive is our chance to improve the world around us, with your views, we'd be here and it would all be pointless?
think about this, if we are all just an accident, then its an amazing coincidence! The universe is so complex that simply being an accident would be impossible...lift the cover of this facade and you'll probably recognise that there is some "force" keeping it all going and safely at that!
