60 million stars: Not one alien detected + Bad news for us if asteroid targets Earth

[Syne]

I’m thinking that adage has more to do with not searching wide and far enough...to prove that fish exist. (or unicorns)

Doesn't work for alien life any better than it does for unicorns. Believing something exists unless you can exhaustively "prove it doesn't" is a typical crackpot argument.

Can’t help but wonder that perhaps scientists have already discovered microbial life somewhere else in the universe, and they are just taking their time to ease into the “announcement” sometime in the future. lol Just thinking out loud.

Would anyone really care about microbes?
Known extremophiles would make that more expected than surprising.
