There are other civilizations out there, both human, post-human and non-human sapients, and many colonies originating from the known world during a 400-year period known as the black moon era, where the reptilian's ability to communicate with their illuminati minions was taken away, allowing colonial empires to explore and settle many of the lands beyond the ice wall. After the reptilians restored their line of communication, they worked to retake control of the earth and realign the course of human history with their grand plan. This eventually resulted in a century long period of war, cataclysm and complete restructuring of society known as the mudflood, where the reptilian-backed new world order emerged victorious and rebuilt the world in their own image. All records of the world beyond the ice wall were erased and earth was once again isolated and unaware of the true nature of their reality. Many colonies established during the black moon era continue to exist as independent nations. but real or not this theory or conspiracy is pretty interesting to read about
