5,000,000,000 BBY

The following events took place in 5,000,000,000 BBY.

Events
Xenobiologists native to the planet of Goroth Prime estimated that their world had developed primitive life by the year 5,000,000,000 BBY, though semi-sentient precursors to the Gorothite species emerged only one million years before the Battle of Yavin, relatively late. The fully sentient Gorothites then emerged more than 990,000 years after that.

Behind the scenes
5,000,000,000 BBY was mentioned in West End Games's Goroth: Slave of the Empire, a 1995 expansion to Star Wars: The Roleplaying Game written by Nigel D. Findley. It was then established in The Essential Guide to Alien Species (2001) by Ann Margaret Lewis as the approximate birth year of the galaxy. The juxtaposition of these events caused something of an issue as it took many millennia to form planets. In-universe, this could simply be attributed to the error naturally incurred when dealing with such early dates; however, The Essential Atlas (2009) by Jason Fry and Daniel Wallace later clarified the year 13,000,000,000 BBY as the approximate birth of the galaxy, rectifying this potential inconsistency.
