I am Earth

As the world greeted the coming of a new year, our MC has been whisked through the passage of time back to the presumed time of the Big Bang. One way or another he survived the ordeal and became part of the Earth, by being its Core. (Warning* Actually the story will have bits and pieces of history mixed in with fantasy chunks and just a different story to anything else that I know of. Having the main start of the story at the beginning of the 21st century with time skips. I will try to avoid it as much as I can but yeah, no promises.)
