"What?" said Karyn, looking where Jon indicated.
"I could swear I saw something... There was a guy there, I know it, and he just disappeared."
"I don't see anything," replied Karyn.
"That wish couldn't have done anything," said Jon. "You know, everyone's descended from women already. I mean, do you know anyone who doesn't have a woman as an ancestor? All the wish could have done was make human beings the dominant species, and we already are! Yet I could swear I saw a guy disappear."
"Jon... you're not making fun of me, are you?"
"No, I really saw the guy disappear. I'm going to get to the bottom of this." Taking the stone from Karyn, Jon said "I wish the two of us know how my wish worked."

The stone affects the whole world... but the space people are from another world. The ones in outer space will notice that their invaders all disappeared. Besides, what about the devices they didn't let us invent? Are they now invented? Could I go inside and find that I have a 3 dimensional TV set and everyone thinks it was always there?"
"Jon, that stuff only happens in sci-fi."
"So do wishes."
"I'm gonna check. You can come inside if you want."
When Jon entered from the porch, he found that there were, in fact, some new inventions around. In fact, right in the living room was...
