Humans share up to 4% of their genetic makeup with Neanderthals.
There are life forms that are on this planet that have survived multiple extinction level events. An example is the horseshoe crab which has been around for approximately 450 million years.
We humans are a stubborn and resilient species. 75,000 years ago, the super volcano Toba erupted. This volcano killed a majority of humans living then, yet we survived. For us to go extinct, the event would have to be more catastrophic than Toba.
