In my beliefs it seems that the Bible indicates before Adam sinned there was no death in the world...... Genesis 3:22-24 and the Lord God said, behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live forever: therefore the Lord God sent him forth from The Garden of Eden, to till the ground from whence he was taken _ That scripture alone tells us that the fruit of the Tree of Life gave mankind healing / immortality. Also mentioned in the Book of Revelation...... Romans 5:12 wherefore, as by one man sin entered into the world, and death by sin; and death so passed upon all men, for that all have sinned. It clearly says Adam's sin is the reason death is in the world and immortality was taken away and further reading tells us through Christ immortality can be regained. As well as 1st Corinthians 15:21-22...... It has been taught by the earliest established churches centuries ago and pass down through the generations, that Adam fell the day or at least the year he was created - and they say the creation of Adam took place six thousand years ago. They completely misunderstood scripture and omitted scripture in their analysis..... A few have come to realize that it was 6000 years ago when Adam sinned and fell from grace. Adam and Eve were fruitful and multiply and had begun to replenish some of the Earth. That is the reasoning why the Land of Nod existed, people were already there: they were the descendants of Adam before sin. Adam and Eve lived thousands of years before he sinned and had thousands of children. Children who migrated over the earth. Scripture had no need to mention the people before sin except for Cain's wife...... we also must remember a day to the Lord is as a thousand years and A Thousand Years is as one day. There is no time limit on God and nothing he does - he is not subjected to time, he established time for man to live by.
