Have you ever put aside every single thing around you from your mind, and start to think about the life that you are undergoing now? If you have, then what came up to your mind? If you haven't, why don't you try to pay some time for this mind thrilling experience?
Perhaps the 5Ws and 1 H Question will be the best way to start our exploration.
What is life?
I personally think that life is something given by a super uncomprehensible power outside of human. Whether you believe it or not, there's something out there which gives the blessing of life to us. Then what is it? Life allows us to breathe, to undergo daily activities(whatever they are, wherever they are being carried out).
what else can you say about life? I already give you some clue, and I believe you will be able to continue this contemplation.
Have fun exploring with your mind.

To live is the opposite of evil; do you see how, if you turn the word around, this is so?

To truly live is to find the good (the God)in all things.
You seem like a very intelligent human.
