> is earth so hostile to life that it will die here, but thrive somewhere else no, idiot. there issue is that there is a non-zero chance of human civilization on this planet being wiped out by some horrible disaster. it's not about all life. no one cares if all the roaches die. it's about us and our society and giants rocks from space, or micro black holes, or radiation from a pulsar, or ai terminators, or some other deadly thing that we aren't even aware of yet. it's better for us as a species if we're not all standing in the same place when something like that happens.
