And they’d never hear us anyway. Our radio noise bubble is weak enough that it attenuates to below the background noise floor in less than 100 light years. We’d need to find a way to spell words with whole galactic arms if we want to get the attention of beings in a galaxy a billion light years away.

There are believed to be at least 10,000 stars within 100 light years of Earth. Planets have been found around a decent fraction of those that have been scanned to date. Of those at least 28 have been found around G class (Sol type) stars IIRC.
