In a universe with billions and billions of galaxies and trillions and trillions of stars, the “astronomically” low probability that all the factors necessary to replicate what happened on earth becomes a liklyhood. Yet given those same laws of physics especially general relativity, it is impossible for biological and mechanical entities to cross those distances and actually visit earth. Now radio waves of various sorts and clever use of earth’s atmosphere as a video screen is another matter entirely. Earth has been broadcasting in analog for 120 years and in digital for about sixty. An overt answer may be forthcoming or has already reached us.
I doubt we'll hear anything anytime soon because there's a relatively small number, if any, of habitable planets in a similar "Goldilocks" evolutionary stage of civilization within "120" light years of Earth.
“the “astronomically” low probability that all the factors necessary to replicate what happened on earth becomes a liklyhood”
Only if there actually is a non-zero probability to begin with, which hasn’t actually been established.
