Exactly. Man wasn't around during the Permian era when damn near everything was exterminated.

What caused the 'Big Five' mass extinctions? All of the 'Big Five' were caused by some combination of rapid and dramatic changes in climate, combined with significant changes in the composition of environments on land or in the ocean (such as ocean acidification or acid rain from intense volcanic activity).Nov 30, 2022
We're good for a few more millions years before we go poof.
We see the spikes in extinction rates marked as the five events:
quote:
End Ordovician (444 million years ago; mya)
Late Devonian (360 mya)
End Permian (250 mya)
End Triassic (200 mya) – many people mistake this as the event that killed off the dinosaurs. But in fact, they were killed off at the end of the Cretaceous period – the fifth of the ‘Big Five’.
End Cretaceous (65 mya) – the event that killed off the dinosaurs.
