You think you know what is life?
Life doesn't begin when the foetus is formed or when cells are capable of reproducing itself. Life doesn't end when cells die or when the heartbeat stops. We, everything, is just part of the Earth resources. For human, we take in Earth resources and pile them in our body, and then there's heartbeat and we are capable of sustaining the body. But one day, we will degenerate and just give everything back to the Earth, as gases or compost.
We are just part of the bigger picture, and we are not at all different from the paper box next to us or the air we breathe. We are just alternative forms of Earth resources. So stop thinking you are at all important and continue piling up resources. Decompose.
