@Chights47,
Quote: Until something is completely 100% proven, it remains, to some extent, to be a belief.
"Proof" is for geometry, just as "belief" is for religion. The increasingly complex facts and evidence that underpin the theory of evolution by natural selection do result in the theory being modified periodically. So far no facts or evidence refute the theory aand that is actually just dumb luck not design. Thats the major difference between nat selection and any "Competing theory" (of which there really are none). All the other "theories" are based upon specific worldviews and religious beliefs rather than facts and evidence wherein these "mere facts" MUST be bent to fit the doctrine at all costs.
Natural selection, has been upended and almost abandoned no less than three times in the last 100 years(All of these revolutions were based upon "evidence" that was later found to best fit the original Darwinian theory). Being able to just drop one and pick up on another competing theory has been the way of science for a long time.
So your assertion that beliefs lie at the center of evolution theory is just flat wrong. Evolution has been developed as a theory and a fact just as a forensic investigation into a murder. All we have is a phenomenon that suggests that life on this planet has not remained static in form over earths history. Darwin had no idea what he was getting into when he began his boat trip. He didnt "have an idea of what he was talking about". His thoughts and the discipline of science occured to him well after he returned and tried to understand some observations he made that were puzzling.
1Why are animals found on islands similar but substantially different from members oif smae genera that are found on the mainlands
2What explained the existence of fossils of animals seemingly long dead but yet similar to major forms of todays animals
3Why did animals and plants on adjacent islands display myriads different forms from each other.
4 How can plants migrate across seas
These and several other questions were slow to develop as Darwin began recording his famous "notebooks on transmutation"
He had no clue of what he was investigating at first. AS evidence presented itself he faithfully recorded it and tried to develop experiments that would help explain and predict what this evidence even meant.
Just like detectives take evidence and try to develop a list of suspects , motives and opportunities, so DArwin slowly began to arrive at a robust theory, of which he still felt was a weak "outline" of a p[ossible dicipline.
Thats the major reason that I reject your belief in "belief". Darwin could have gone in a multiple of directions. He could have been a better indformed poet who hintede at "transmutation", like his grandfather. He could have posted theories like Buffon 's or LAmarck's. But he didnt, as his evidence and experimental results
matured, his theory began to take shape maybe twenty years before he published and the remaining 20 years or so were QA and novel experiments and gathering geologic data.
Belief never guided his path. In fact, as his theory matured, he penned several apologias concerning why he and Christianity were taking different paths. He began doubting Biblical "science" quite early on his boat ride (As he read Lyell) but he wasnt really a mature agnostic till much later .
