"Exactly—and we're standing on it! Maybe there was a planet called Minerva outside Mars, and maybe it had a civilization on it. Maybe the Ganymeans took a few animals there and maybe they didn't. But it doesn't really matter anymore, does it? Because the only planet Charlie's ship could possibly have taken off from, and the only planet they could have aimed that Annihilator at, and the only planet he could have seen in detail from Luna—is this one!

"They were from Earth all along!

"Everyone will be jumping off the roof and out of every window in the building when this gets around Navcomms."

Chapter Seventeen

With the first comprehensive translation of the handwritten notebook, the paradox was complete. Now there were two consistent and apparently irrefutable bodies of evidence, one proving that the Lunarians must have evolved on Earth, and the other proving that they couldn't have.

All at once the consternation and disputes broke out afresh. Lights burned through the night at Houston and elsewhere as the same inevitable chains of reasoning were reeled out again and yet again, the same arrays of facts scrutinized for new possibilities or interpretations. But always the answers came out the same. Only the notion of the Lunarians having been the product of a parallel line of evolution appeared to have been abandoned permanently; more than enough theories were in circulation already without anyone having to invoke this one. The Navcomms fraternity disintegrated into a myriad of cliques and strays, scurrying about to ally first with this idea and then with that. As the turmoil subsided, the final lines of defense fortified themselves around four main camps.

The Pure Earthists accepted without reservation the deductions from Charlie's diary, and held that the Lunarian civilization had developed on Earth, flourished on Earth, and destroyed itself on Earth and that was that. Thus, all references to Minerva and its alleged civilization were nonsense; there never had been any civilization on Minerva apart from that of the Ganymeans, and that was too far in the remote past to have any bearing on the Lunarian issue. The world depicted on Charlie's maps was Earth, not Minerva, so there had to be a gross error somewhere in the calculations that put it at 250 million miles from the Sun. That this corresponded to the orbital radius of the Asteroids was just coincidence; the Asteroids had always been there, and anything from Iliad that said they hadn't was suspect and needed double-checking.
