[Star Wars] Where do Human's come from?

Human's are a very common species in the Galaxy and yet unlike Twi'leks, Zabraks, Hutts amd other distinct races we don't know the planet they originated from. Is there any information that sheds light on the subject?

Ohh you have to love wookieepedia. Here is the answer, though since cannon has changed recently then they might change it.

Having a recorded and civilized history reaching back far beyond the beginning of space travel,[4] the origin and early history of Humans was lost to their scientists in the depths of millennia. Whatever the original homeworld was, it was universally accepted that Humans evolved on one of the Core Worlds near the galaxy's center. Humans were among the few sentient species in the galaxy whose homeworld was unknown, the Ryn, Yoda's species and the Baragwins being some other examples.

According to an inscription found by archaeologists Dr. Ualp Xathan and Fem Nu-Ar on Seoul 5 around 4 ABY, Humans originated on the planet Notron,[5] an archaic name for Coruscant.[54] The ancient Zhell nations, who drove the Near-Human Taung from Coruscant, may have been the progenitors of later Humans.[4] Coruscant's ground had been several kilometers below its inhabitants' feet for millennia, with the lowest depths of its planet-wide city dating back to 100,000 BBY. Thus, it was impossible to carry out the historical study and archaeological research on the planet's prehistory necessary to prove or to disprove that theory. In addition, Coruscant's natural climate was said to be too cold to support Human life,[55] a claim difficult to be reconciled with the theory that it was the original Human homeworld. Tarnese Bleyd believed that the ancestors of Humans favored trees and high ground based upon his observations of human hunting behavior. [56]

It is possible that some ancient civilization, such as the Celestials or even the Rakata, transported early Humans from their original home planet to others. It was, in fact, alleged that they had once been a slave race of the Infinite Empire[4]; however, any knowledge of Human enslavement was absent from Rakatan records as of 3956 BBY. Some of the far-flung 'colonies' eventually diverged genetically from the Human baseline, giving rise to various Near-Human races and species.

During the Jedi Civil War, the Jedi Revan discovered evidence in the oral traditions of the Sand People on Tatooine that the human species may have originated as slaves taken from that planet by the Rakata, the Sand People being the genetically distinct species that evolved from those who were left behind. The fact that the Sand People's legends indicated that the planet had once been far more temperate and habitable before an ancient war with the Rakata adds credence to this possibility. However, millennia of distortion introduced into the historical record combined with the Sand People's extreme hostility to the idea of introducing new interpretations into their oral tradition made it impossible for Revan to investigate this further.[57]
Expansion

Humans discovered space travel themselves, early in their history; in fact, they were already present on a few scattered colony planets of the Core Worlds even before the development of hyperdrive, thanks to the use of sleeper ships. Coruscant had grown to a planet-wide city and from there, they spread to such Core Worlds as Alderaan, Corellia, Corulag, and Chandrila.[4]

During their early history, Humans seem to have been subjugated by the Rakatan Infinite Empire. Though some sources indicate that they were enslaved workers on Rakatan projects such as the Star Forge,[4] the fact that the droids and computers Rakatan ruins on Dantooine dating from that era did not recognize the Human species points to the contrary.[58]

After the fall of the Infinite Empire circa 25,200 BBY, the Humans of the Core used Rakatan technology to set up a true interstellar civilization. At first, a network of hyperspace cannons linked Coruscant with other Human-populated worlds, as well as the Duros civilization. Corellian Humans were one of the first societies to develop hyperdrive starships sometime before 25,053 BBY, spreading the technology to other Core Worlds. With the hyperdrive, their scouts and explorers traveled and met with other species, in a time known as the Expansionist Era.[4]

The Human colonies, which had expanded through the Core Worlds through slower-than-light travel, later established daughter colonies of their own in what became the Colonies region. During the last pre-Republic years, Humans reached the Outer Rim and populated planets as far away as the Tion Cluster. The Tionese warlord Xim the Despot, whose conquests reached from the Cronese Sweeps to the Si'Klaata Cluster at the edge of Hutt Space, was one of the most prominent Humans of the pre-Republic period.[4] 

TLDR: Coruscant then taken as slaves by space aliens and spread around the galaxy. Also the explaniation talks as if it isn't confirmed because its using in universe explinations from characters a thousand years later. But in the Dawn of the jedi comics, KOTOR games, and the guide to warfare book it gives direct answers that yes humans are from coruscant.
