Adam died age 930 years, on the day of the anniversary of his creation, states ancient Jewish writings.
Yom Kippur, the Atonement, was given to the Adam creation by God, at the fall, to rehearse yearly, at the turning of the years from creation, and to look forward to the Atonement of the promised Kinsman/Redeemer.
Moses did not institute it, but confirmed its relevance and sacredness of the promised Messiah who was to come.
Many of the tribes descended from Noah kept the yearly sacrifice as Adam had taught, but as Paul said, in
Romans 1, "all men once knew/all nations once knew, but corrupted the truth, and changed the image of God..."
Israel was elected as the tribe through whom the promised Messiah would come, who would be that final acceptable Atonement; and that, for Believers in this Church age, was at Passover; but for the unbelieving nation of Israel, God will reveal that for them at their ordained Yom Kippur, at the end of the seven years of their time of trouble, which is yet to come: and which will be the final one for them, when He reveals Himself to them as their brother/Kinsman/Redeemer/Messiah/Salvation; for there will be no more Yom Kippur sacrifice for the first death of the Adam creation in Israel, for the millennial reign, for that will be finished to them, for them, once, for all, when they see their Messiah in person; and they will greatly mourn for Him, their brother/Kinsman, as the prophets state.
