Ok, so i was playing skyrim when i noticed that the moon in skyrim is waaaay closer than that of earths. So here's my theory. Skyrim is actually based on another planet, the Daedra are the inhabitants of this planet, and everyone got there after earth was way destroyed, making this game actually in the future. the reason there are earth animals is because sme scientists brought samples of each animals in cellular form with them to try to establish a new earth, but the Daedra all attacked and it caused a big war, producing some ruins that you cant find accounts of in any books. eventually all of mankind was restarted and history began again, causing people to think and act like they would in the past and using swords instead of guns. And the fact that there are also creatures not on earth now may mean that they either were genetically altered animals or they are natural inhabitants of "Nirn". What do you think
