I went back 15,000 years to an ancient civilization.
I took a lot of awesome stuff with me.
Flash lights, batteries, electronic toys …
… lots of hi-tech gadgets that didn’t need infrastructure to work.
They were wowed. They thought I was a magician.
Some people thought I could prophesy. So they came and asked me questions about the future.
Since I had a time machine, I could even shine a little in that area.
They loved that. They thought I was a god or something.
But one of them was extraordinarily astute.
She confessed to being astounded by my abilities.
Then she asked if I could make her infinitely happy forever.
I said no.
She said “Then you know no more than we do.” and left.
