Certainty without humans or other spacefaring life all other species on Earth will go extinct. Does that really matter in the grand scheme of things or is it just ego? edit: To take it further, without some super-intelligent / supernatural beings it seems likely all structure in the universe will eventually disappear due to a heat death or a big crunch. Does even that matter? My take is that we are just too young to have any idea what really matters in the grand scheme so the best approach is just try to survive.
