Maybe because we are alive.

It would be foolish to think that we live just to cater our desires, such as eating, reproduction ..and everything that is connected with the senses, just enjoy and after die. In this case we doesn't differ from animals. I know that you can say about science, developing, but what about those people who are cripple, etc. So, our existing has a special aim here, just we should think and we will open the truth.

Maybe because it is necessary.

Cause God wants me to live and He has a plan for our life.

    Why are you born?
