Amazing post, great job thanks I learned a lot. So many movies, books, myths etc. Even in religion. So many references to something below us. Really mind blowing when you think of everything. I also remember some video I watched years ago on youtube. A normal mainstream educational video. It talked about the overall progression of an intelligent race. The video said through technological advancement and need, a race could one day be able to kind of build a massive structure around an actual literal sun and use the energy to its advantage and basically live off of it. Sorry if I sound crazy but yeah lmao just makes me think!
