It's come pretty close, and that's typical. Most species that have ever existed on this planet went extinct ages ago, often during periods of drastic climate change (as far as we can tell from the archeological record.)
Our own fairly recent past is the same. The latest research on the 'flood' that gave rise to flood myths in every civilization in Southern Europe, the Middle East, and North Africa, suggests that the Mediterranean Sea was a fertile populated valley during the last ice age. But when the ice age ended due to natural climate change, the rising Atlantic broke through the natural dam at Gibraltar and flooded the valley, and into the Black and Red seas, up the Nile, etc. That's a massive natural disaster that must have wiped out a pretty big chunk of humanity. It was probably repeated on a smaller scale around the world too, as seaside villages were flooded out by the rising oceans and likely increase in the number of storms as the world warmed up.
