Forum:Bigfoot in the gamefiles?

There is so much debate about wether or not bigfoot, leatherface, a ratman and ufos appearf in the game, cant someone just look through the game files and look at all the npc models and just see if any of them are there? im not gifted in this feild personally, but i knwo you can do it on other games, is there some reason we cant do it in gta?
