, the inhabitants of these planets are still aware that their ancestors came from Earth, but this does not make them fond of the place. Rather, they develop a racist theory by which "the best strains" had left Earth to colonize the other planets and left "the inferior strains" behind. However, they have no choice but to ask the help of the protagonist, a detective from the despised Earth, to solve murder mysteries which baffle their own police. Afterwards, Earth embarks on a major new campaign of space colonization, with the hope that the new colonists will prove more faithful to the Mother Planet than the earlier ones. However, in the end of the series, the Earth is doomed to a slow radioactive process that will leave the planet uninhabitable, causing a more rapid expansion of colonization from Earth.

By this time, Earth people still believe themselves to be the original home of Humanity, but hardly anyone else shares this belief. Fanatical priests, based in a mysterious Temple erected on the ruins of Washington, D.C., cultivate the mystique of Earth's ancient glories and conceive a plot to spread a Terrestrial disease throughout the Galaxy and in this way take over the Empire (and incidentally, act out the stereotype). The plot is foiled by a middle-aged tailor from the Twentieth Century, who possess powerful psychic abilities as a result of experiments performed upon him when he arrived in the future.

. Others remained to form present day Earth societies, which interact covertly with other extraterrestrial races and civilizations, many of them human. Earth first became important in the scene after the Alterans occupied it as their new capital (its name was Terra Atlantus at that point). When they were forced to relocate to Lantea in the Pegasus galaxy (circa 65 million years ago), they "seeded" the planet with a less advanced form of themselves. Eventually, the Goa'uld found the planet and determined that the human body is the ultimate host body for their parasitic race. Many humans were kidnapped through the Stargate the Supreme System Lord Ra brought to Earth (Earth already had its own Stargate in Antarctica but it was inoperable) but the leftover population wasn't touched; they eventually rebelled and drove the Goa'uld off the planet in 3000 BC. About 8000 BC, the Lantean remnants returned to the planet but the primitive civilization extinguished their last hope of rebuilding their once great civilization due to the presence of the Goa'uld; as such, the Ancients slowly died out since their numbers were too small to survive, even by crossbreeding with regular humans.

With Earth largely left alone for millennia, its human population continued to advance until the rediscovery of the Stargate in 1928 and its subsequent reactivation in 1994 (since its DHD activation device was missing, they had been unable to determine its purpose until they were able to create a computer interface). Unlike an enormous majority of planets, the Stargate on Earth was kept secret from the general populace to prevent widespread panic because "we are not alone".

 killed Goa'uld Supreme System Lord Ra and started a guerrilla war against the Goa'uld. However, its importance pales in comparison to the power of the System Lords or the Free Jaffa Nation, even though after the extinction of the Asgard and the defeat of the Ori, the Tau'ri became the dominant race of known space — although they were initially at a huge technological disadvantage, they later managed to reverse-engineer Goa'uld technology to the point where they started building their own ships, though much of it was rendered obsolete when the Asgard granted a significant amount of non-weapon technology. The Tau'ri also created remarkable technological feats, such as fighters equipped with hyperdrives powered by an unstable isotope. Their power increased further when they discovered that, due to crossbreeding with Ancients before their extinction, some Earth-born humans actually possessed a unique gene required to operate some of the more advanced Ancient technology. The peak of their power occurred when the Asgard donated their entire technological knowledge to Earth prior to their extinction; with this and some Ancient technology, the Tau'ri actually surpassed their precursors and defeated the Ori.

, Earth is the homeworld of humanity and notable as one of the few places that "The flower of life" (the source of the powerful energy source Protoculture) can grow. In 1999 during a global war the (future) SDF-1 an alien warship crashed to Earth on Macross island. Discovering they were not alone in the universe (and in secret the fact that the SDF-1 was a warship for a giant sized alien race) the human race united and rebuilt the ship as well as using the technology to advance their own and to create a small defence fleet for earth.

Ten years later the ship was ready but as preparation for launch on a mission of exploration continued Zentradi warships arrived in orbit to search for the ship. Though humanity tried peaceful contact a booby trap in the SDF-1 fired the huge main gun at the Zentradi committing Earth to a devastating interstellar war. To lure the Zentradi away from Earth the SDF-1 attempted a space fold FTL jump
Faster-than-light
Faster-than-light communications and travel refer to the propagation of information or matter faster than the speed of light....

. This went wrong transporting not only the SDF-1 but part of Macross Island, 70,000 civilians and two navy warships to an area near Pluto. Pressure held in sub-surface shelters long enough to evacuate the civilians while the ships were grafted on to the SDF-1 as flight decks. However the jump also caused the FTL drive to vanish (for unknown reasons) as such the SDF-1 had to return home under normal thrust fighting Zentradi all the way and unable to talk to earth due to jamming.

During the conflict many Zentradi became fascinated by Earth culture and over a million ships eventually defected. The ship finally returned to Earth but was driven back into space to draw off the Zentradi again. However the Zentradi bought over four million ships to Earth and bombarded the planet. The SDF-1 took out most ships with an overload of its shield system but in the process the ship was left incapable of flight and most of the Earth's population was killed. Over the next two years the survivors tried to rebuild and at last the Earth began to green again.

Twenty years later the Earth had recovered during the war with the Robotech masters, but even after Earth's victory the planet was then attacked and occupied by another set of aliens The Invid in 2031. The Invid collected what they could of the Protoculture on Earth but seem to have left the population (now millions once more) largely alone.

In 2042 the Robotech Mars expedition returned from deep space but was wiped out by the Invid during the battle to liberate the planet. The survivors were forced down to Earth where they hooked up with the local resistance groups.

Two years later a massive fleet arrived with more advanced technology given to them by the alien Hydenites. The Invid quickly left Earth rather than risk Earth's destruction by deadly weapons the Neutron_S missiles which were far more dangerous then man believed. As Humanity celebrated however the Hydenites were revealed as the Children of Shadow who had destroyed the Invid homeworld eons before. They launched a sneak attack on the human space station liberty. Another war then began.

 by David Brin

Glen David Brin, Ph.D. is an American scientist and award-winning author of science fiction. He has received the Hugo, Locus, Campbell and Nebula Awards.-Biography:...

, there was a semi-mythical species known as the Patron that started the Uplift cycle—adopting a pre-sentient race and over a period of a hundred thousand years of selective breeding and genetic engineering, raising them to full sentience. As a result, most sentient species in the universe are members of various clans and factions, often quite powerful, with varying beliefs.

Earth was overlooked and humans evolved, evidently without a patron race. However, by the time of first contact with galactic civilization, humans had themselves raised chimpanzees and dolphins to sentience, giving the human race a claim to patron status. This claim is provisionally accepted by the major institutions of galactic civilization even as it is hotly contested by a number of senior patron races.

Galactic civilization holds humanity's claim of having evolved to sentience independently to be highly controversial at best, and an offensive heresy at worst. Some clans holding the latter view have actively conspired to have humanity's patron status officially vacated and to adopt the "wolfling" race themselves, thus gaining three sentient races and control of "fallow" genetic material: Earth's wealth of species with uplift potential. Only the conservative and ponderous nature of galactic institutions and the rivalry of other clans reluctant to see the Earth's races claimed by another have prevented this.
