What is life....!!!!!

A true quetion for everyone is what is life.......
I started survey on this and found the following answers -
1) Life is nothing, however .......life is zero for me........but don'nt know the definition.
2) Very strange, till now you don't know about life......I think Life is a biological term, which presents conceptual thinking and many things....cann't describe....
3)Life is a thing of entertainment for me , I do not know about it more...as I never think about it....
4) Mujhe kya pata main toh abhi bahut chhota hoon, maine abhi life ko dekha hi nahi hai ,achhi tarah........
5) ask this question to Any Saint not to me......

I heard many view from other, but still at the same point..can anybody help me in this matter.....
