What is life without a struggle? Everything in existence struggles to survive and exist to the best of it's ability. From people to rocks, they are all struggling.
I propose to struggle means there is some 'magic' involved. If we were to observe that everything struggles, is everything alive? If you were to hear fairy tales about rain drops having a 'soul' or what have you, that everything is intertwangled with everything else, and we are consciou, then we would have one world consciousness, relating to determinism. With this we could plot the relationships between things, and then again that is science!
The world is intertwangled all the way up to the top. From a meteor existing only to run out of steam of hit something in it's path, there is existence. But why do i say they are alive? Thety no blood and tissue, and cannot act. That is because everything reacts and reacts only, as the seeing to of an action, right at the beginning of time would mean that the first thing to exist was alive - something quite unlikely, yet, if we take into account what i have 'drawn up' then you might say there was consciousness in the big bang or whatever you want to believe.
Then you would have to look at what life is. Is a human being alive? Surely. Is a plant alive? Yes. Is a rock alive? Well, it does grow to become a larger rock if watered, so is reactive, yet is not biomass. Finding similarities between biomass and 'mass' would lead us to believe that they both react. So, what is the difference?
The differences could be down to reproduction. A rock reproduces! it has tiny shards of it rubbed off and they become rocks too. this could be how the universe reproduces and grows? the universe could have atoms 'rubbed' off of it and they could start to grow into new parts or pieces of the universe. The biomass is only different in a way, what way? How is biomass different from nonbiomass? Is everything biomass?
