As long as we're ok with the fact that by this definition, it's easy to make artificial life and we already have. (Take the entities from any sort of evolution simulator.) I guess you would call that "digital life", and contrast it with "physical life". EDIT: I'm confused about the downvotes. To be really concrete, the swimmers in Darwin Pond[1] seem to me to satisfy all of OP's criteria for life. Do they not?
