In the year 3030, on a distant planet located more than 300 light years from Earth, whose civilization disappeared 500 years ago, a group of explorers has located at the bottom of a crater a spaceship that apparently crashed there hundreds of years ago.
Maybe it tried to land and they failed in the attempt, that is, an unmanned vehicle launched into space from somewhere in the galaxy or outside of it.
What has most confused explorers is that in it, completely sealed, there is a container in the shape of an ark, without any inscription or anything that can identify its contents.
After ascertaining the structure of the ship they can verify that it is an unmanned artifact, made of a material that does not exist on the planet and that has remained intact despite the inhospitable place and the time that has elapsed.
Taken to the laboratory and after an examination with rays, which if they manage to penetrate the thickness of the walls, they are surprised to discover that the ark is empty, that there is no solid element inside it.
After exhaustive meetings between the rulers of the planet, they decide to open it, assuming that there may be something that the lightning has overlooked and for this purpose and assured that it does not represent danger, they make the event a public party.
No one knows that the object is terrestrial and that inside it is enclosed a powerful virus that was one of the causes of the extinction of terrestrial life.
A virus that arrived on the planet from space through a small meteor and was able to survive the fire of the entrance to the atmosphere to finally infect from small insects to the population, in such a fast time that it was not possible to get an antidote.
Which is why a significant number of humans and some animals were sent to emergency stations to try to get a similar planet in the cosmos.
