All dates for the time of the Flood and the creation of Adam are wrong. The Flood occurred at 3820 years from the Cross with Jesus at 32 years old. Three things indicate this. Ezra closely estimates the date of Adam to 5500 years BC. In II Esdras, he dates the time of Adam at 5000 years from his time at very close to 500 bc. This is because there are two missing time periods in the Bible. One is 1258 years from the death of Joseph to the beginning of the Captivity in Egypt. The other is 2 years in the 70 years of Exile. There were two 1 yr. breaks in the siege of Jerusalem. The second indicator is the recurring 1000 year famines. One occurred in 2200 BC. A massive famine dried up Egypt, the Nile, and the Middle East, ending the pyramid age. My findings indicate that the famine of Joseph happened 3240 from the Cross, almost exactly 1000 years back. It was massive also, and everyone came down into Egypt for grain from Joseph. Interesting also is that I found a reference for another famine 1000 years later in 1200 BC. The Romans mentioned a famine in 200 BC. In 800 AD I can't find a mention of any famine, though there might have been one. I don't know of one in 1800 either. This is still a mystery, and I have not heard any scientists mentioning this, though the one in 2200 BC was discussed on a History Channel episode. The third is my "Designed Plan of History" in my book. of the 6000, 2000, and 1000 year history of the Adamic age, the plan itself is 5994 on the left side, and 3078 on the right. Of this range, all but the 1260 years mentioned are accounted for. Adam was created 5508 from the Cross with Jesus at 32, very close to Ezra's 5500 yr period. Ezra claimed to know the exact day of Adam's creation, but we don't know the day of that particular writing.
