"There's no moral to this story, it's just a bunch of stuff that happened!" - Homer Simpson
Everyone has to have a blog about the meaning of Life. Here's mine ;]
So at least once in your life, you will debate about the meaning of Life, even if it's just to yourself, or friends, or some random jerk on the Interwebs. Everyone debates about the meaning of life. Why are we here? What's the point? Did God just put us in a snow glob to watch us destroy ourselves? Is there even a God? Questions we may never know the answers to, even if we die.
No, we don't know that. We invented jobs to make money, so we could survive. It's our way of trade. I'm not saying jobs are pointless, but most we're made just so we'd have money. Life get's more complicated, people get more stupid as things get easier, so we need someone smart to do shit for us.
Ok now back on topic. I don't think we were each put on this Earth to do something specific for the rest of our lives. I think we were put on this Earth to just do good and right. Help someone in need, be a vent for a friend, teach right from wrong, just do good. Maybe it's an experiment for God to see if a bunch of people with different thoughts and ideas can get along, and not destroy themselves, and learn to accept eachother.
So like Homer said, maybe there's no one point to Life, maybe it's just a bunch of events that all happened, just because they did.
