Plus, the only way alien messages would be bouncing off our satellites is if they are super high powered(all the nuclear reactors in the world) narrow band laser beams more advanced then anything we have. AND POINTED AT US. If there are alien radio signals out there, they are so dispersed by range that it wouldn’t matter or not.
There can only be 2 reasons we haven’t heard from intelligent life elsewhere.
1.) Space is way way way way way too big. It’s simply not possible to send a understandable message over dozens of light years, well I take that back, probably possible. But you would have to have a habitable planet within dozens of lightyears(there might be one, probably none). So you’re talking hundreds, thousands, millions of light years. Nope not gonna get that phone call.
or
2.) There aren’t any intelligent species.
Aliens WOULD NOT , encrypt their messages if they were trying to contact “EARTH” from light - years away. They just wouldn’t.
“Aliens WOULD NOT , encrypt their messages if they were trying to contact “EARTH” from light - years away.”
BUT they MIGHT encrypt their messages if they only wanted responses from a civilization capable of decrypting their messages. All lower life forms need not reply. Just sayin’
