You ARE attempting to 'make the rules' because you are using invalid and out-of-date definitions. The problem with basing any valid science on some dictionary sourced life definition has been well understood known for a long time (except, evidently, in your case). From the NASA viewpoint, in order to make use of the idea of abiogenesis in forming testable hypotheses, another approach is used. From the NASA 2015 Astrobiology Strategic Roadmap (page #144):I read it. I might even agree.
But I’m using the definition used by nasa and Harvard in OOL
If you don’t agree give an alternative definition of life or abiogenesis?
I’m genuinely curious!
If The definition of life is precise, so must be the definition of the moment of abiogenesis. How do you blur a definition of life?
I don’t make the rules.
I just thought it curious that the definitions they do use , leads inevitably to irreducible complexity. It’s called the law of unintended consequences!
btw - notice that for example a “self replicating” polymer by autocatalysis Is not by definition living. So the definition does not prevent some complex precursors.
Reorienting the approach, in order to escape the obvious conundrum and turning the origin of life topic into a useful, testable hypothesis, of practical applicability:What is Life?
First, comprehending life is a conundrum. Clearly, we need to develop a working concept of the entity whose origins and cosmic distribution we seek to determine. This will help to identify the “services” that an environment must provide in order to sustain life, and it helps to identify and interpret any signatures that might indicate its presence. This, in turn, will help to identify past or present planetary environments as promising candidates for exploration. However, without at least a second known, independent example of life it is probably not possible to determine with great certainty the characteristics that are unique to terrestrial life and those that are truly universal for all life. We have little choice but to begin by identifying attributes of life that are universal among living systems as we know them and that are relatively less likely to reflect adaptations specific to the historical trajectory of habitable environments on Earth.
Those physio-chemical functions only imply (logically) universal life functions, based on our already known-to-be singular the Earth-life case. The approach is all about avoiding specifically what you are doing via your beating-everyone-over-their-heads approach .. please desist with this and acknowledge the reality of the more modern approach(!?):Recent studies (e.g., Baross et al., 2007) have proposed the following necessary set of universal attributes of life: (1) life must exploit thermodynamic disequilibrium in the environment in order to perpetuate its own disequilibrium state; (2) life most probably consists of interacting sets of covalently bonded molecules that include a diversity of heteroatoms (e.g., N, O, P, S, etc. as in Earth-based life) that promote chemical reactivity; (3) life requires a liquid solvent that supports these molecular interactions; and (4) life employs a molecular system capable of Darwinian evolution.
All you have demonstrated in your posts throughout this entire thread, is the complete uselessness of going down the so-called Irreducible Complexity avenue of a rabbit-hole enquiry, which is based purely on the philosophically based obsession with the belief that logic alone, can establish a so-called 'Truth' about the origin of Earth-based life.These attributes imply the following basic universal functions: (1) life harvests energy from its environment and converts it to forms of chemical energy that directly sustain its other functions, and thus, life requires useable sources of energy; (2) life sustains “metabolism,” namely a network of chemical reactions that synthesize all of the key chemical compounds that are required for maintenance, growth, and self-replication, and, thus, life needs chemical “building blocks” and an appropriate solvent to host these reactions; and (3) life sustains an “automaton,” a multi- component system that is essential for self-replication and self-perpetuation (Von Neumann, 1966), and, thus, life needs information-rich chemical compounds and favorable environmental conditions in order to sustain this complex machinery.
The above thoughts might be just a starting point in our pursuit of a universal concept of life. Clearly we must identify and pursue a path that leads from our Earth-centric thoughts ultimately to a concept that is truly universal.
Meanwhile actual science marches on with practical investigations capable of producing tanglble progress on questions about life origins.
