A Human says what?

[Paleophyte]

Your point is taken but I believe that the claim was that humans didn't survive the last five extinctions. This is correct. Our distant ancestors survived them. The ones that saw the K/T fireworks were likely some form of tree rat that was barely a primate. Claiming that humans survived the last five extinctions would be akin to claiming that you fought in the Punic War because your great-great-grandfather was Italian.

Evolution is fluid, not static. If a single one of our ancestor species had gone extinct, this is precisely the as saying the human lineage went extinct.

No, it isn't. If one of our ancestors had gone extinct we would never have existed. Don't make me get a time machine and your grandparents' address to prove this point.

Since that clearly didn’t happen, the statement ‘Humans survived the five extinction events’ is true both semantically and scientifically.

You are conflating humans with their ancestors. H. sapiens hasn't been around for more than about 300,000 years. There are unquestionably grey areas during speciation but the differences in time scales being discussed handily avoids that issue. In the most recent major extinction our ancestors were tree rats that were only tentatively primates. During the Permo-Triassic extinction they were therapsid reptiles that you'd have a hard time distinguishing from a dinosaur. At the end of the Archaean our ancestors were single-celled organisms bereft of an organized nucleus. None of these were humans in any sense.

Your claim is akin to the notion that the Greeks won the battle of Salamis using Nimitz-class aircraft carriers. Obviously they didn't. They used triremes, the distant distant ancestors of modern ships. It is possible to note the relationship without confusing the two.

Simple point: We all evolved to this point.

One look at a fundamentalist proves this wrong. It's obvious that those things emerged from the dirt some 6000 years ago and haven't benefited from one jot of evolution since that dark day.
