Scientific definitions of life - Life as an autonomous agent or a multi-agent system capable of reproducing itself or themselves, and of completing at least one thermodynamic work cycle. Another difinition is - Life is a self-organizing, cannibalistic system consisting of a population of replicators that are capable of mutation, around most of which homeostatic, metabolizing organisms evolve. I feel life is too complex to be defined wid ease... Life offers lotsa opportunities, ppl who grasp them r d ones who make the most out of wat life has to offer ;)
