I find it more likely that they (the space aliens) would observe from a distance. Maybe even send probes. But also we can’t really assume much because we’re looking at it through a human perspective. We have no idea what evolution of thought, philosophy, empathy, etc. looks like in intelligence outside Earth. Perhaps they are more hive minded like insects. Or philosophically cold and stoic - does empathy exist as a concept for them? Emotions? We know what ‘human’ reasoning looks like. Unless of course there is some sort of evolutionary constant across the universe we can’t really assume much if anything IMHO.
