In the First Book of Adam and Eve, Adam gets quite excited when he is told he could come back into the garden in five days and half a day. When God realizes the mistake he tells Adam that a day is a thousand years. It is really five thousand years and five hundred years. Adam went back to his cave.

Some say the deluge occurred near the end of the last ice age in about 13,000 BC. By this reckoning, Adam was born around 14,000 BC and the five thousand, five hundred years were up in 8,500 BC. This is about when Jericho was built. I've seen nothing in the ancient record to indicate Adam got back into the garden just as the precursors of Civilization in Mesopotamia were being established.

These gods were new here, still suffering from start ship lag, not quite used to the new earthly sun cycle. They were still on their star ship clock. There is a 3.6 to 1 ratio between the two clocks. So, in this case, the one day is as thirty-six hundred Earthly years. This puts the end of five and a half days at 5,800 AD, about another day.
