Biological evolution is but one aspect of evolution. Unless of course you don't think you are evolving as a human being.I know that. I am discussing the origin of life for no other reason than it deserves to be discussed.Ok but how did the first living cell come about?Evolution is not a theory. It is a hypothesis. I trust you recognize the difference. Evolution does not qualify as a theory because it cannot be disproven. There are no scientific experiments that can be conducted on it. There is no scientific evidence to back it up.
Sorry, but that’s nonsense. Scientific theories start out as hypotheses. A hypothesis is given theory status when either by experiment or many observations (and observations of that hypothesis's predictions) prove to be true. Any hypothesis that attains theory status must also meet some other criteria. It must be able to make testable predictions, and it must be falsifiable. That is, observation or experiment could show that it can be shown to be false (or true).
Now, evolution has a great amount of observational evidence to support it. It also makes predictions (for example, that bacteria and insects can become resistant to anti-biotics or certain insecticides), and these predictions have been observed. Evolution also makes predictions about what we should find in the fossil records, and for the most part these have proven true. The observations support the theory. The Cambrian explosion was explained by a slight modification to the theory, called punctuated equilibrium, which again is supported by the evidence. Not only that, but DNA structures common to different life forms is highly suggestive of the truth of evolution, as evolution would predict exactly that this should be true, and observation and study of DNA structures thus far confirm that prediction.
I don't pretend that I know.
However. the inclusion of abiogenesis in any discussion of Darwinian evolution is a rhetorical tactic, not a genuine discussion of evolutionary science. Biological evolution (Darwinian or otherwise) presumes the existence of life, and it does not matter what the source of that life might be. It could be abiogenesis, or it could be panspermia (directed or otherwise), or it could be the miraculous intervention of a god or gods, or it could be some other source of which we are completely unaware; it does not matter.
Evolution studies what has occurred to life in the subsequent 3+ billion years of its existence. It explains the origin and diversity of species, not the origin of life.
As for evolution. Evolution is not limited to living things. Evolution is when anything changes from a less advanced state to a more advanced state. Matter and energy were created 14 billion years ago. It started as subatomic particles, then quickly changed to hydrogen and helium, then through supernovas changed into all the elements and compounds that we see. Eventually matter made the leap to living organisms. How it did so, no one knows. But only a fool would believe the amino acids assembled themselves. And the amount of information required for sequencing is staggering even for a single cell organism. Ultimately matter which was created 14 billion years ago has evolved to the point that it became self aware of itself. Now that's evolution.
So quite literally, we are made of star dust. Just like it says in that 3000 year old book.
"Evolution is when anything changes from a less advanced state to a more advanced state."
Sorry, but that defines a fundamental misunderstanding of biological evolution. Evolution is not directional. It does not advance inexorably from dumb to smart or from simple to complex. The impression you have that it does so is merely (again) the human tendency to impose our own biases of social progress onto a natural world that does not share them.
Sometimes evolution does makes things more complex (bacteria to annelid worm, for example). But sometimes it makes things less complex (free living organisms to degenerate parasites, for thousands of examples). Most of the time it does neither. The only direction evolution always moves is towards “more fit.” And since the definition of fitness is dependent on and changes with the environment, it is a constantly moving target.
