People are married to the belief in survival of the fittest and that the fossil record must show gradual change because that's what everyone sees.
Why shouldn't people see evolution in the fossil record? That's what it represents, unless you believe somebody planted them such that the forms most resembling contemporary forms appear in the more superficial strata and with younger ages radiometrically. You accuse others of tendentious interpretation of the data to support a preconceived notion, but that's what you're doing. Like the creationists, you have decided that you don't like the scientific interpretation of the fossil record, and so reject the only reasonable understanding of the evidence.
If true then why not parse "metaphysics" as "basis of science" or at least tell me what word you're willing to accept to mean this?
I just explained to you in the last post that you have defined metaphysics with a vague phrase. I don't know what you consider the basis of science to be.
We have a rule in contract bridge, where opponents are entitled to ask you what your partner's bids mean ("What did his three club bid mean there?"), that you answer specifically, not with the name of a convention, such as, "That was an Reverse Bergen raise," since the opponents might not know what that means. A proper answer is, "It shows 10-12 points and four-card spade support." Every bridge player understands that second description, but some would not understand the first.
Can you do something similar and choose words that have more specific meanings than "the basis of science"? Give me a sentence or two I can agree or disagree with. Did you see my definition of metaphysical. Did you understand it? I don't ask if you agree - but did you understand it well enough to agree or disagree?
I never used to notice that religious people made sense and have good arguments ofttimes because I couldn't get past their premises. People make sense only in terms of their premises so if you reject all the premises it's easy to miss the sense.
That's why I reject theology and all scripture associated with an alleged deity. It's basic premise, that a god exists, is insufficiently evidenced and thus unshared (not mine or any atheists' belief), and thus no conclusion, however valid the reasoning, can be sound.
The evidence purported is that humans have some physical characteristics reminiscent of fish. That's the evidence scientists apparently use as backing up their claims. And let's not forget the land walking fish types. That is also, I suppose, claimed evidence by scientists who say that humans evolved from fish. Over billions of years, of course. Not overnight. It is also not proof tested by watching fish develop ability to breathe out of water, grow feet and eventually leave water entirely as their basic necessary breathing environment.
I would make the same comment about your posting as I did to cladking. Your words, like his, are what it looks like when somebody has decided that they don't like where the evidence leads others. You've described the world one might expect to find in which human beings had piscine ancestors, where human embryos develop through a stage with primordial gill slits and branchial pouches, and where transitional forms between finned, obligate marine vertebrates and tetrapodal, amphibious vertebrates are found. Yet you will not be persuaded. Your answer: "Not proof," as if that were a rebuttal or even relevant.
That's a choice. You choose not to be among the critically thinking, scientifically literate. But you shouldn't expect others to have much interest in what you believe instead if they have to ignore evidence to believe it.
I've read about these things. They still don't explain how exactly things are dated like billions of years ago, do they?
They don't explain it to you. Nor to anybody else who either [1] has never learned the fundamentals of the science or [2] has a stake in not understanding (or both).
