Serpent is the symbol of a megalith, a megalith being Stonehenge, the tempter of is in the tree/pillar at the center of the garden . The older version of the Persian garden had either one, two, or three trees with a fountain built around. The three trees are; life, destiny and knowledge(which match the lines on the palm; the lines on the palm match Yahweys Palm Print the architecture of the Khufu Pyramid ). The serpent is a modified dragon; both words have been used to describe megaliths. A megalith is a pillar/tree used to measure the shadows of the earth in its orbit around the sun. Almost all churches/temples/synagogues/mosques/etc. are built on top of remodeled megaliths.
