If they confine their analysis to species that would leave fossils, would that satisfy you?
I believe mollusks and vertebrates would fossilize under the right circumstances. So, does the science indicate an extinction is underway among those groups?
The answer is yes. To the extent that we have relevant data, it suggests that a mass extinction is underway.
We really only have two choices: Pretend we know nothing, or compare the extant data with what we already know.
