Do we even have a meaning?

I'm going to be honest. I have no idea what people were made for or why we're here. I've heard many things and just can't seem to understand. "God put us here to help with the planet.", " God put us here so he could better understand people.", "We just developed over time from apes and became smart.. because we can." I want to know why, not how. After asking hundreds of people and deciding nothing, I thought "Hey! Maybe there isn't a reason and we're just here..."
Yep.. For a while I thought that, and still think that way. Maybe Aliens put us here to see if earth could still support life after the dinosaurs. Now, over time, we just have no point. we survived the test aliens put us through. That evolution theory... have you heard of the missing link? How did we get from apes to humans? I believe the aliens reproduced with some time of ape and "PLOP" here we are ^-^ ( the missing link : http://en.m.wikipedia.org/wiki/Missing_Link )
After the aliens found life can still survive here on earth, they decided to help us get started with life ( helping us build things like the mysteries found in Egypt and what not) but they never told us our purpose. So we basically have none. I'm not saying it's ok to end lives just because there's no point to live... in a way we have a purpose, we just don't know what it is. Just think about it though, what do we do? Nothing. We are alive to work and breed. That's it. We go to school so we can work, we work to make money, we make money for shelter and food to survive, we survive to breed, and we breed to have more people so that the cycle keeps going. Over time we all work for others survival. Doctors, entertainment, control, and guidance. That's all we're here for.
Remember, this is just my opinion. I'm not trying to change anybodies mind on anything.
