I can't believe there are people willfully obtuse enough to still be putting out this strawman. No one credible is or has ever claimed "the end of life" or even "the end of multicellular life". Humanity could get wiped out entirely and "life" would be fine for a few billion years until it really would get wiped out completely without intelligence. But even a few tens of millions let alone hundreds let alone billions is something we might reasonably want to avoid don't you think? Is this really such a hard concept for you to grasp? When "life survived" previous mass extinction events you should read that as "SOME life survived, and often not the big complex types."
