On July 28th, 2009 the first alien scout ships flew through the skies of earth. The next day, the first wave of weapons fire hit several major areas across the world, followed by several explosions in the skies, then the attacks ended. 

For the next decade, the world took the time to repair and rebuild what was lost. The United Earth Organization was formed.

Only then did the United States and Russian governments divulge the Stargate technologies and the alien ancient outpost that fought back the extraterrestrial threat, opening a new era of exploration through the Stargate.
