An irregular signal would be more of a sign of intelligent life than a wave that is pulsing.
Unless the sound has a recurring beat that you can dance to.
Does anyone believe that IF this is the Real Deal, that the ones responsible will actually confirm this? I seriously doubt it. The only way to confirm the existence of extra terrestrial life is the way it was done in “Independence Day”. They show up in ships no one on Earth could have ever built.
I believe that life in the Great Out There does exist. It’s just getting a super honest confirmation of it. How many lies have the sheeple heard over the years about this?
Still, it would be neat if it was real. Get on your iPhone and return the call.
