25,000 Years ago

==Upper Palaeolithic, Late Stone Age on Earth ==

The first human inhabitants of Australia make the crossing from southeast Asia Palaeolithic hunter-gatherers use mammoth tusks and bones to support hide-covered tents at Dolni Vestonice

Technological advances included significant developments in flint tool manufacturing, with industries based on fine blades rather than simpler and shorter flakes. Burins and racloirs were used to work bone, antler, and hides. Advanced darts and harpoons also appear in this period, along with the fish hook, the oil lamp, rope, and the eyed needle.

The changes in human behavior have been attributed to changes in climate, encompassing a number of global temperature drops. These led to a worsening of the already bitter cold of the last glacial period (popularly but incorrectly called the last ice age). Such changes may have reduced the supply of usable timber and forced people to look at other materials. In addition, flint becomes brittle at low temperatures and may not have functioned as a tool. == Galaxy and Universe==

The first known Y’All invasion around 25,000 years ago.

Little is known about that invasion, except that the Nul and the Klack were among the galactic civilizations that fought the Y'All and suffered terrible losses.

The Klack have only limited historical records but know that at least twenty galactic civilizations were completely wiped out. If there were any earlier invasions is unknown.

The Saresii did not have any space ships or contacts to other civilizations after the Dark Ones destroyed their colonies.

Prior to the Nul joining the Union, they did not share their historical records. While that has changed, as of 5050 (OTT) researchers in the Nul archives had not found any records that can be linked without a doubt to that or an earlier invasion.
