simpley for us as musliems this is State of the Holy qoran explains Why live:

( I created the jinn and humans for nothing else but that they may serve Me )

explanation:

 I have not created them for the service of others but for My own service. They should serve Me, for I am their Creator. When no one else has created them, no one else has the right that they should serve him; and how can it be admissible for them that they should serve others instead of Me, their Creator.

Ah...., already though somebody would bring that mister Allah here again!! There are people here that cannot do two postings here without saying Allah, Koran or Mohammed.

Anyway, the reason why we are alive is that the instincts of our parents was to reproduce and have children, like any living being. They made us. So the basic reason to live is to follow your natural instincts that will give you a satisfied feeling. Most of those natural instincts are then to be traced down to the natural need of a species to reproduce: love, sex, food, taking care of your offspring.

It's pretty simple and logical.

beat me

i guess our lives are preisless if we aren't serving a purpose (parents are taking care of children,students are learning ,doctor are healing sick people) , but from my religion point of you " we are here to be god's hands and gods maen proving we are here to worship him by following his orders so from this some of us will go to heaven and some others to hell"

ask your parents, they started it
