Human Expansion into Atlantis (Isle of Atlas)

Humans originally settled in Atlantis around 10,000 BCE. Hunter Gatherers go from Europe to Atlantis during the Ice Age. A temporary ice/land bridge was there for them to cross over. The ice was incredibly strong, but yielded no usefulness except ice for water. Once on Atlantis, humans start to farm. This developed their society faster than humans who hadn't crossed to Atlantis yet.
