One thing to keep in mind is that the time interval of stability for Earth as a life-bearing planet is actually fairly close to the end. We&#x27;re past the 75% point. The Sun&#x27;s evolution will &quot;soon&quot; put an end to that (speaking on a cosmic scale).<p>So it seems like it was a close call. Life needed almost the full extent of that interval of stability to create an (arguably) intelligent species. There can be no reset and start over. This is it, for the solar system. If we fail to survive, this whole star and its planets have failed to produce viable intelligence.<p>If Earth turns out to somehow be unusually stable as a life-bearing planet, this might explain a large portion of the Fermi paradox. This might be a large chunk of the Great Filter.
