“Here’s a theory: maybe you find the oldest fossils in the areas that never got scraped clean by glaciers because they never got scraped clean by glaciers, not because there were never any fossils as old anywhere else :)”
The evolution hypothesis must necessarily be dependent on evidence found in fossils. And, who knows? Perhaps the “Answer” to the great mystery lies beneath a two-mile thick glacier.
That’s why we have hypotheses (i.e., working theories).
“The evolution hypothesis must necessarily be dependent on evidence found in fossils.”
Which is a primary weakness of forensic-type speculative “science” as opposed to the harder, experimental varieties. You have no control over what evidence you will find, and you cannot know how much evidence you are missing.
