It is 16,000 years ago. You are a caveman, wearing skins and carrying a flint knife. You are fully and completely human, Homo Sapiens Sapiens, and although you think all things have existed since the dawn of time in fact your own species is still only about 30,000 years old, born in this same ice age. You are young, about 14 years of age, and about as half as old as you ever expect to get. Half as old as anyone you have ever met, except for the ancient shaman who guards the cave before you.
Today is special.
Today you will meet one of your gods, an important one, the God of The Hunt, the god to whom you prey for the beasts to fall beneath your spear, so that you and your tribe can eat. Today you will be shown mysteries, so that you can become a better hunter, and a fully initiated adult within the tribe. It is night, and some of your tribe are with you by the small fire, preparing you for the ordeal ahead. This place is special. Before you lies the cave entrance, and beyond it are magical forces that you can barely imagine but for which you have the utmost respect.
