"How many of these beings were there, father?"
"Exactly three million and forty-one male adults and three female adults. These creatures first appeared on Earth on the island of Sardinia. In five weeks' time they were the masters of the entire globe."
"Didn't the Earth-lings fight back, papa?"
"The humans warred against the invaders, using bullets, ordinary bombs, super-atom bombs and gases."

"What were those things like, father?"
"Oh, they've passed out of existence long ago. 'Ammunition' they were called. The humans fought each other with such things."
"And not with ideas, like we do now, father?"
"No, with guns, just like I told you. But the invaders were immune to the ammunition."
