Earth was also the homeworld of the domesticated house cat, who later in space evolved into Felis sapiens. The catfolk revered Lister as a god, who was still in stasis aboard Red Dwarf at the time, and as per Lister's plan they set off in the Cat Arks to search for their holy land, "Fuchal", which was actually Fiji on Earth. One of them crashed into an asteroid, and it is unknown whether the other actually found Earth (although the events of "Identity Within" would seem to suggest they set up a colony elsewhere).
The Space Corps also originated on Earth, as did various artificial intelligences and GELFs, which spread out into the Galaxy. The hologram Rimmer was quick to point out to Lister that, even if Earth still existed, it was extremely likely that Lister was the last human alive, three million years into the future.

In the novel Infinity Welcomes Careful Drivers, it is revealed that a giant toupee was installed over the Earth to cover the hole in the ozone layer, (also refered to in the original version of the episode Marooned).
In the novel Better than Life it is revealed to have been voted for by humanity as the dumping place for all of interstellar civilization's garbage. This was also used to remove the large number of captured GELF prisoners of war from the GELF revolt, as they were trapped on the planet. Due to a methane buildup, the planet quite literally farted out of the solar system and into Deep Space, where it entered a long, dark ice age. When Dave Lister saved the ship and crew of the Red Dwarf by shooting a planet out of the crash path of the ship, the whole star system was reshuffled. This led to the troubled planet's gravity knocking Dave Lister and Arnold Rimmer onto the Earth inside of Starbug. Rimmer eventually lost his remote connection and reappeared on Red Dwarf, but Lister was trapped on the planet alone with no food.
Due to the Earth being moved near the system's sun, its ice age melted in a single night - which led to Lister being the only human ever to sleep through a melting ice age. After nearly being corroded to death by acid rain, Lister finds himself in a landscape made up of green glass bottles - the remains of humanity's garbage. Lister finds himself in Mount Rushmore in the American state of South Dakota. Lister is continually "attacked" by the Earth in the forms of earthquakes, oil rain, and lighting, and the paranoid part of his mind begins to suspect that the planet is desperate to keep humans - the ones who so hurt it - off its surface. Lister is spared after he swears to try and make it all right again and, with the help of giant cockroaches, start rehabilitating the planet for the next thirty-six years.
