Godzillas possible new origins and his possible first attack

I believe that in Godzilla 2014 Godzilla will still be a transformed godzillasaurus and that in 1945 when the atomic bomb hit Hiroshima and Nagasaki the blast from the bomb either hit it so it was knocked out or he was in a slumber when the bomb hit him and then in 1954 the Japanese most likely woke it up somehow and when it awoke it was fully transformed into Godzilla and then out of kaiju instincts it left the island it was on and headed for Tokyo and when he got there his atomic breath blew up and burned Tokyo the military was sent in but there weapons didn't do any thing so Dr.sarizawa created the oxygen destroyer and used it against Godzilla but to no avail because before he could activate it Godzilla killed him and destroyed the oxygen destroyer and so they used nuclear bombs against him and he disappeared so they thought he was dead but my guessing is that those nuclear tests created more kaiju but I'll get to that some other day. and in my first post I couldn't write in the discussion box so yeah.
