I wonder ( If those hypothetical civilizations are out there ) just how advanced they would be ? Could be observing us now ? Weighing us in the balances & finding us wanting ? Would they intervene in our affairs if we show we’re not interested in blowing ourselves up, poisoning this world, stripping our world bare of resources, then moving on to other planets ? Part of me would be curious to find out, part of me just likes to ponder this mystery. This universe seems too grand & large for all known life forms to be concentrated on 1 small planet orbiting a medium – size class GO2 star in arm of this sized galaxy.
