The Sumerian pictograph for the "GARDEN OF EDEN" is the letter X, which is a form of the Cross with sides joined into a square, called the Tetragram or Square Cross. This ancient symbol is important because the square is the Sumerian pictograph/hieroglyph for the word "MA". It designates the square Lake where the Sun sets, which is the Oma-mbala Lake in Anambra State, Nigeria. X is the Sumerian hieroglyph for the word "GAN" (Garden of Eden), and it is the popular symbol of Osiris, and it marks the Oshuru Shrine in Lejja where the Sun rises.
An X inside a square as in the Bosnian example is also the pictograph for the Sumerian word "MA-GAN" MA (X) and GAN (SQUARE) both designate the Rising and the Setting points of the Sun, whose hieroglyph is the crescent moon enveloping the sun disc as eternally represented in the Lejja Table of the Sun in Enugu State. By this eternal symbol, the Sumerians provided the proof that the Garden of Eden is in Nigeria. The symbol of the X within a square is the popular Mbari symbol of the Mother Goddess OMA, found in all Mbari shrines in Igboland. It is the representation of the Sun/Son in the Womb of the Mother Goddess, which the Igbo call "Mgba Nnechuchukwu".
