most of these are pretty valid reasons why it would be premature to expect to encounter aliens now. i think we also tend to forget that even if there were civilizations at our own tech level right next door, astronomically speaking, their radio and television signals would be unreadably attenuated by the time they reached us. there might be music and images in the faint static our radio telescopes pick up, but it’s so scattered and degraded we’d never be able to tell.
just moving along like everyone else
