Use the following statement as a basis for writing a story.
“There’s a planet at the edge of the universe not unlike the earth in landscape and atmosphere. But its inhabitants are not.”
It was believed that should the end of the world be imminent, it would be a suitable place to migrate to, and governments worldwide had made provision for the elite, the extremely rich who could buy their own passage and a selected few to be transported there in shuttle ships.
A surveillance team had been sent ahead, but on their return the news was not good, and only half of the crew had retained their sanity. The scientists and psychiatrists tried to understand the implications, but quadruple trillions of dollars had been invested and no-one really wanted to rock the boat for the saviour of Mankind or be responsible for its extinction.
As it happened, it didn’t matter as the returning craft was infested with the seed of the alien planet. In no time at all, the virus took hold, spiralling out of control as it piggybacked on anything and everything, mutating as it went. It was the reason their species had survived for millennia, adapting to their environment and claiming it as their own. Within two years the Earth would be just another planet at the edge of the universe, just like a hundred others.
