  1. The movement of protein bodies, as Darwin said, and then Karl Marx echoed him, not fully understanding what was said.
    From the point of view of physiology, quite an exhaustive answer. We are all made up of protein compounds that are constantly changing. Otherwise, all processes on Earth would be static, and therefore – without development-dead.

  2. Terrestrial life is a mode of existence and reproduction of nucleic acids (“genes”). Proteins are just a useful tool in this process, which, apparently, was not present at the initial stage. In its simplest form, terrestrial life probably arose spontaneously in an aqueous solution of abiogenic free nucleotides as RNA molecules (or ensembles of such molecules) having catalytic activity and capable of self-reproduction.

    In general, life can be called any self-reproducing systems that have heredity (the ability to pass on their properties to “descendants”) and variability (the transfer of properties is not ideal and occurs with errors – also inherited). With limited resources, such systems will inevitably compete, and “errors” (mutations) will provide material for natural selection and evolution. This definition includes, of course, virtual “life” simulated on computers , including for purely practical purposes (for example, the so-called evolutionary algorithms, but not only them). Therefore, it should be supplemented with a restriction: objects must actually exist, and not be simulated in virtual reality.�

    The requirement of spontaneous generation (spontaneity of the appearance of the first “ancestor”) it seems excessive. After all, even now a person is able to create a viable cell, whose genetic information from the first to the last nucleotide is artificially synthesized. Well, if self-generation is not necessary, then some self-replicating robots, originally created by humans, will also be a form of life. If they are able (by themselves or together with other self-replicating robots) to extract the necessary resources, they can, in principle, further evolve without the intervention of their creators and form a kind of inorganic biosphere (for example, as in Lem in“Invincible”).

  3. The answers to this question, it seems to me, do not have much meaning, because nothing new will be said to the author of the question, everything has already been said and retold more than one hundred times. And each answer is not even an answer, it is rather a desire to speculate.
    Each of us understands perfectly well that “living” is fundamentally different from “inanimate”, that these are two completely different states of matter (?), but no one can really say what their difference is.
    The following is interesting: at what stage of organization does a living mother turn into a “system” that uses chemical elements and their compounds for its functioning, manages them, and at the same time consists of these same elements? Somehow, in the world of simple chemical elements, a similar “system”was organized. All right, but where is the “inanimate” pumped in and “life” begins: amino acids – proteins-organelle – living cell?
    A living cell is an unimaginable thing, it is the greatest achievement (of evolution), it is an artifact, because human thought will not be able to understand for a long time how such a thing can be done and whether it can be done at all. This is probably why scientists do not go there, but pay more attention to changing and rebuilding what they already have.

    Let's assume. We took ribosomes, many different proteins, dna and rna molecules, put them all in a certain vessel with a liquid that does not injure their structure and contains the “necessary” chemical elements and amino acids. What do you think will happen in this vessel and will anything happen at all? It seems to me that following the “logic of life”, something like “well-coordinated” processes should start happening there, and if so, this is enough, because it is clear what it will all lead to, sooner or later. And if we leave this vessel “empty “(even with amino acids and “necessary” chemical elements), will we see anything like this then? I mean, there is a certain “barrier”, a certain phase transition from “inanimate” to “living”, which we cannot yet understand and, moreover, reproduce. This is probably why there won't be a clear and unambiguous answer to your question.

  1. There are two forms of existence in the causal process. Passive and active. Passive form — when some part of the world exists only in response to external causes of changes. This part is inanimate. Active form — when a part of the world is organized in such a way that its structure is free in relation to the world. This part is alive. A living being independently chooses to react or not to react to external causes of changes, has a will. If the whole world existed in a passive form, it would be completely deterministic, there would be no fun. It would move along the only possible trajectory. Life is capable of reorganizing the world very much. There is even a fantastic theory that life originated in order to prevent the destruction of the universe. Living beings will develop so much that they can create their own comfortable indestructible world.

  2. The ocean.�

    This is such a broad concept that, like God, it includes almost everything. Professional scientists and their loyal fans have some strong opinions about this. I don't want to argue with anyone. I'll just say my own.

    Life is all there is. Without life, there would be no universe. The universe, life, god – all these concepts are by and large identical, since they describe the totality of being. Life permeates everything, and the universe is made up of it as much as the ocean is made up of water. Every cell in your body is alive, look through a microscope at any point on any surface – you will see the same thing. I take it as a strong possibility that life is not necessarily based on carbon compounds, on matter in general. There is so much that we do not see, do not know, do not understand, do not feel. This endless ocean takes on millions of different forms, it flows from one to the other, never stopping its flow, but at the same time remaining unchanged. Out of space, and at every point of it, out of time, and every moment. Life is the eternal, infinite foundation of all foundations, the first foundation. Life is everything. Your parents, the animals in the zoo, the bacteria in the intestines of a dead cat in your basement, everyone you know, anyone you've ever seen.

    And most importantly, life is you. Life is what you have in common with everyone. All-all, without any exceptions, divisions by color, race, political preferences, number of legs, length of tail, size, complexity of the nervous system, density, materiality. Knowing this, you can look into the eyes (if there are any) of any living organism in the universe, and say -” we are of the same blood, you and I.” And even if you are horribly devoured after that, it will not matter, because your body will die, giving food to another body, and the part of life that you are will continue on its way to become someone else. This is an eternal process.

    I know that all this will seem like utter nonsense to many. And I accept your right to think so, your right to have your own beliefs, your own worldview.

  3. Life is a form of the existence of matter. But it has its own distinctive properties. We can distinguish something alive from something inanimate (a stone is inanimate, a dog is alive, based on what conclusions?).

    It is some properties that make life life, namely:
    – organization of (higher-order structure: the cells and went);
    metabolism (metabolism) to maintain the organization;
    – the ability to grow and develop (at the expense of metabolism);
    – adaptability;
    – response to stimuli;
    – reproduction (reproduction of their kind);
    – the availability of genetic information and its transmission to posterity;
    – the ability to die.

    Compare the stone and the dog by these characteristics, and you will understand why the dog is alive, but the stone is not.

  1. Life is the flow of connections with other people and events that surrounds us, and these are our experiences of these events. This is what we do every minute from the first to the last breath.

  2. Life is an entropic process that stands in the way of the establishment of Order. An eternal process of creation and destruction, ensuring the non-equilibrium of the system, its incompleteness.

  1. This is definitely not the way protein bodies exist (c) Vovan the First, Undead Ghoul.

    The mode of existence of protein bodies is different. Превращ Turning into scrambled eggs, digesting by chewing, or whole ingestion by a boa constrictor… and so on, and so on.

    Life is a biological evolution. �The process of local decrease in entropy, increasing the complexity of the biosphere as a result of the competition of species. �In general. �In particular, we call life small fragments of this “big picture”.

  2. Life is a deadly sexually transmitted disease.�

    Just as you can't see a mountain while sitting on a mountain, you can't definitely say that we exist until we go beyond it

  3. Life is a continuous process of movement, both physical and non-physical. This is a kind of fractal. The essence of life is to make changes (preferably for the better, development) and continue your kind.
