Looking From a Larger Perspective

Looking from a larger perspective, what is our value? Why do we exist?

I wonder why are we created? Or is there even a reson for our creation? We live for several years and throughout the days of our lives, we do things, we experience things, we think, we feel, we wonder....then, we die. What's our purpose? Just like an ant to a man, are we just small, weak, fragile creatures to someone bigger? Are we something unimportant, living without a purpose, with a definite end, with a known fate to someone supreme? Why are we able to think, to feel, to question our purpose, our existence?
