It is established in Terror of MechaGodzilla that the Black Hole Planet 3 Aliens had been operating on Earth for several years, since they are shown transforming Katsura into a cyborg in a flashback scene.

As for those old people in Godzilla vs. Hedorah, they're just grumpy onlookers who are watching from a distance because the party at the top of Mt. Fuji is only for young people. It's a nice little fan theory, but there's absolutely no chance of it being true.
