“All life forms should enter the bunkers at this time,” the One said. “Our survival depends on avoiding detection. As we suspected the spacecraft will take up orbit. ”

Below the planet’s surface the deliberations began. “We knew they would come,” Lifeform A said. “Yes, their greed knows no bounds,” Lifeform B said. “I propose a first strike,” Lifeform A said. “They are too close.” The other lifeforms assented and relayed their decision to the One.

“Agreed,” the One said. “We shall wait until they have weakened themselves. It is only a matter of time before their squabbling results in nuclear war. Eradication will be a simple matter.”
