After watching all Heisei Godzilla films I had something that confused me! In Godzilla Vs King Ghidorah we can see that the future people erase Godzilla when he was a young creature. But if they erased Godzilla it means that the timeline changed? Godzilla 1985 and Godzilla Vs Biollante never happened? Here's more. In Godzilla Vs Spacegodzilla the scientists explain the origin of Spacegodzilla which strangely they mentioned Biollante being responsable of the origin or Mothra. But why Biollante!? The other Godzilla was erased from history in Godzilla Vs King Ghidorah! And the other question is... If Biollante never existed then Mothra IS the answer of Spacegodzilla origin? Or maybe another origin I don't know.
