Bronze Age
The earliest known Ugarit contact with Egypt (and the first exact dating of Ugaritic civilization) comes from a carnelian bead identified with the Middle Kingdom pharaoh Senusret I, 1971–1926 BC. A stela and a statuette from the Egyptian pharaohs Senusret III and Amenemhet III have also been found. However, it is unclear at what time these monuments got to Ugarit. In the Amarna letters, messages from Ugarit BC written by Ammittamru I, Niqmaddu II, and his queen, were discovered. From the 16th to the 13th century BC, Ugarit remained in constant touch with Egypt and Cyprus (named Alashiya).
Mu (lost continent)
There is evidence that the civilizations of the Americas and the Old World developed independently of each other and, in fact, agriculture and urban societies probably first developed after the end of the Ice Age, somewhere in the Levant some 10,000 years ago and gradually spread outwards from there to the rest of the Old World. The development of the oldest known cities, such as Çatalhöyük, can more easily be attributed to local and gradual evolution than to the coming of refugees from a "superior civilization".
