>>In my view, Darwin should have formally declared life as an axiom or postulate in his theory. Contentious disagreements have multiplied from inferences due to that omission. <<
And since I am having insomnia, I’ll go ahead and address this question (if’n you don’t mind).
Abiogenesis is no more a prerequisite to TToE (or any other biological science) than it is a prerequisite to Geology, Astronomy or any other life science. Darwin was not looking to the origins of the Universe, merely the origins of biology.
Because TToE is an emotional area, people feel that it has to qualify itself based on a different set of criteria than do other sciences. But, if the first question to a radioastronomer or geologist is not “but when and how did the Universe begin?” then it is equally irrelevant to demand an answer to that question of an anthropologist.
The information itself is not physical but may be, and may be measurable in bits (which are not necessarily binary under Shannons model) providing the Shannon entropy is measurable.
In sum, information under Shannon is the reduction of uncertainty (Shannon entropy) in the receiver (or molecular machine) as it moves from a before state to an after state.
It is the action of a successful communication, not the message or data itself.
It doesnt matter if the message is DNA, a punched card, combination of keystrokes, a letter in the mailbox, a folder in the file cabinet, a database, a record, DVD, spoken word, thought, radio, television or TV content and so on.
Likewise the channel, encoding or decoding are merely elements. As long as sender and receiver speak the same language, the receivers uncertainty can be reduced by successful communication. The channel might be the airways or a wire or the USPS and so on.
That letter in your mailbox does not become information under Shannon until your uncertainty is reduced, i.e. you become informed.
Information under the Shannon definition is not physical per se.
Likewise I am successfully communicating when I pray to God, and God of course is not physical, I am the sender, He is the receiver. The spiritual channel of my prayer is not physical. And when God communicates to me, e.g. that Jesus Christ is Lord, that also is not physical.
That is the big difference between the words of God and the words of men. The words of God are spirit and life. The words of men are neither spirit nor life.
But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know [them], because they are spiritually discerned. - I Corinthians 2:14
Bottom line: there are no non-physical causations and they can not be created out of whole cloth from argumentation
And there is great resistance to this among scientists who tend to be empiricists. Mathematics is only quasi-empirical.
For instance, the concept of infinity is very useful in mathematics but it doesnt translate well to a finite universe.
Null is mathematically informative and in cosmology particularly helpful in contrasting a zero dimensional singularity to the absence of space/time and physical causality itself. But to other disciplines of science, it may be altogether unacceptable the closest concept some can embrace is a vacuum which also exists in space/time and is therefore subject to causality.
What is the end of the extension of one divided by three, or pi?
And so on.
In appreciating the physical world through the Spiritual eyes of a Christian, to recognize that God is The Creator, His Name is I AM and that Jesus is the Word of God, Logos one expands his domain to glimpse the unknowable.
