I didn’t realize this was an unpopular opinion, until a BBQ last week. Sure, somewhere in the universe life may exist, granted, but there is not a shred of evidence any ET has ever visited Earth or sent a signal.

My only, somewhat serious, disagreement is the signal comment. If they did send a signal and it’s in a spectral band we monitor, we monitor a small percentage of the sky(low single digits) and even if it was from one of those areas, we’ve only been doing that for less than 100 years(probably closer to 50). If species sent a rf signal which arrived here during the French revolution we would never of noticed.
