I Like the idea of. Godzilla having been acknowledged by ancient civilization for example the people of Odo Island worshipped him as a God like dragon and preformed rituals and sacrifices or keep him at bay when fishing was poor. Unfortunately their myth came true
Oh, neat. At first I thought this was just in reference to Emmy from Gvs.KG, albeit slightly off in appearance, then I realized this was a reference to Game of Thrones. I like the carving in the background. It seems to be prophesizing those Dorats are going to have some fierce opposition when they grow up. Either that or that carving is depicting the past and that is the Dorat's parent or progenitor.
The babies (also known as Dorats) are sent back in time to the very island were the nuclear bombs were dropped. The blast somehow had the same effect on them as it had on Godzilla, and fused all three of them into Ghidorah.
