And Edwards specifically stated his vision for the movie as "What if this stuff actually happened?" His goal isn't just to change the backstories of these things to make them realistic, it's to keep them as similar as possible to the way they are in the Toho movies while making their real-world consequences realistic. There's no logical scientific explanation for giant monsters, but in the universe of the movie, they are nonetheless real somehow and humanity must find a way to survive against them.
