You return to stone age, what will you do?

Hey, this morning I got this crazy dream which I would like to share with you.

I saw that I made a time machine and tried to go back in the past to see how huge inventions were made. Accidently, I travelled to the time of discovery of fire. Now that takes me to the stone age, or something before that. And guess what, my machine broke down and I was stuck there in that era what seemed to be like forever. I saw some people, of that age, coming towards me and made me their GOD. Now how do you react to that. I tried to speed up their evolution process by teaching them modern stuff, but they didn't understand what I was trying to say. No language known. Also they didn't understand sign language since the signs I was making of anything are based on modern objects they don't know anything about. There was no way to even respond to them. There was nothing in that camp. Just nothing and there was no tool available with which I could fix my machine. I started with teaching them stuff which man has learnt in course of evolution and time, like stone age things, weapons to hunt, wheel, etc.

What would you do in such a situation?
