I just explained to you (in the previous comment)that everything has energy, that even the vacuum itself has a temperature. No matter is totally inert and cold. By your definition, everything is alive, nothing is dead, nothing can possibly be dead, dead does not exist. And if there is no death, then its opposite, life. cannot exist either.

You are confusing "energy" with "entropy". Entropy is the amount of disorder. To decrease entropy you must use energy, which is just another way of saying that if you want to build something from nothing you have to work.

Living things manipulate and use energy, use it to transform themselves and their surroundings. They reverse entropy on the local scale, by increasing it on the larger scale. Living things use the energy available in their environment to make themselves more complicated. This is life, metabolic activity, growth, reproduction. When living things die, they stop doing this, they rot, decay, and become less complicated.

When hydrogen atoms in the sun fuse into helium, they become simpler. The radiation released travels to earth where a tiny piece of it is intercepted by plants, which use it to assemble nutrients into tissue, which is more complex than soil and water. The total amount of complexity is much less, but in the tiny piece of space and length of time that is the plant, its tissues are more complex.

Total overall complexity decreases (which is another way of saying entropy increases. Entropy is the amount of disorder.). But the universal flow of increasing entropy is temporarily reversed by the plant. It uses energy to do this. So as the universe winds down, becomes simpler, (entropy increases) here and there little pockets of life briefly reverse entropy and become more complex.

Its like water flowing downhill. The net flow is in one direction, but here and there you may find little temporary eddies and whirlpools where the flow is reversed, that burst forth briefly, and are then whisked away. That is life.

A living thing is a machine that consumes energy and decreases entropy. All machines do this, although we don't necessarily think of them as alive. All living things are machines, but not all machines are alive.
