I love WH40K so much but im not gonna sit here and act like the lack of water on terra isn't retarded af lol. Even if the earth was nuked out by all sorts of heat the water would only be irradiated boiling oceans away is absolutely stupid bcuz if anything like that were to happen horrific earthquakes would constantly shake and slide whole contented around violently! That's not even talking about the fact that the earths biosphere would have completely vanished and become no better than current day Mars essentially making it an eternal dustbowl. But bcuz I love 40K the way I do and the universe is basically fantasy land I look past the goofy writing on the science of it all lol.
