The earliest continent currently theorised to have existed was Ur about 3 billion years ago. About 1.8 billion years ago Arctica, Baltica and East Antarctica merged forming Nena. Then about 1 billion years ago Nena, Atlantica, and Ur collided forming Rodinia which held together for about 750 million years. Finally about 300 million years ago Pangaea formed from Avalonia and Laurentia and was itself broken into Gondwana and Laurasia about 100 million later.
