95% of ELE events on earth .. wouldn't necessarily destroy earth forever... most likely it'd just be rough going for a few decades or even a couple hundred year

95% of ELE events on earth .. wouldn't necessarily destroy earth forever... most likely it'd just be rough going for a few decades or even a couple hundred years, so if you can build 'backup colonies' in space and humanity can survive just long enough for the earth to be hospitable again, then we can come back and re-populate and destroy it all over again. :)
