well see as far as every scientific definition ive seen really has many faults, that to be honest i dont know how you'd fix, like we could literally make life in a way... a robot can build others like itself, and be self-suffiecient, does that mean it has life? what determines what we consider a soul?is it the ability to make decision, because in that case then nothing has life, because our decisions are based on physical properties in our mind and other stimulants........ this is really a question that cannot be answered because before you can determine what is alive, you need to define life, and about the only definition you could go with would be "not dead".
