Why are we on this earth ?

According to the great Vedic scriptures, we are all here because we wanted to be. We wanted to be "God," so God gave us a world to play in, and pretend in. However, after trying to be God for awhile, we should come to the point where we realize we're not very good at being God, so finally start making choices that help us remember who we really are, and what our relationship with God really is. Then we can return to the world where we are truly from. Our purpose is to come to this realization. Unfortunately, most of us have no desire for true self or God realizatin. Scary business. So we just carry on with our material businesses in this material world, and convince ourselves that's all there is. You should go with your gut feeling. Always keep searching, and inquiring, about what life is about. The answers are there within you. Good luck.

As for me, I believe god made us and put us on this earth to worship him. So the ups and downs in life we get through is a test for us. It's a test whether we believe Him and that no matter what happens we still worship him. So that we die and go to heaven. Whereas the people who is fooled by money or fame or other things that comes in life and failed to remember God will have their punishment when they leave the earth.

I believe there are many different reasons for being here. I do believe part of our purpose is to serve the Lord, that is if you believe in a higher being. We are all here to make some kind of difference. I think that as we go throughout life we might not know what our existence is for but one day it will all make sense.
