Millennium

The Bible tells the Story of mankind, from Adam and the preparation of the earth as Adams home. Then because of the moral failures of Adam, Eve, and the animals, God judges them and death comes into Adams world and he and his children lose their immortality and perfect health. Their genetics are altered and they begin to live shortened lives, this includes the animals.
In the original garden home, they all lived protected, blessed lives until the sin of disobedience entered and they were rejected from the garden, man's perfect habitat. But before they left the garden, God promised to start the restoration of the world to its original condition, and allow Adam and his children to live there again. The earth itself longed to be restored to its original state and to return to the perfect garden habitat as it was.
The coming restoration will take six thousand years, six days, to accomplish and then continue one thousand years more, a seventh day, as the earths day of rest, Shabbat, this last day is, Millennium.
