Genesis and man's creation
Some Jewish traditions place the creation of Adam and Eve, found in the first chapter of the book of Genesis, at exactly 8 a.m. in the morning of Elul 29 in year 1 (the last day of the first Hebrew civil year). This date corresponds to Friday, September 26 in 3760 B.C. (Julian). Roughly ten hours after this believed creation was the start of not only the weekly Bible Sabbath but also the High Holy day known as the Feast of Trumpets (Rosh Hashanah).
The above date, which is open to considerable debate, would admittedly fulfill the Biblical requirement that man was created on the sixth day (sunset Thursday to sunset Friday, see Genesis 1:31) and then rested with God when the Sabbath arrived at sunset Friday (Genesis 2:1 - 3). BibleStudy.org's current research places the creation of Adam and Eve in 3969 B.C.
The oldest person in history
The oldest person to have lived is Methuselah (Genesis 5:27), who almost made it to celebrate his one-thousandth birthday (he lived 969 years). He is in an elite group of humans who lived for more than 900 years. The others are Jared (5:20), Noah (9:29), Adam (5:5), Seth (5:8), Cainan (5:14) and Enos (5:11). The average life span of the eleven generations born before the flood, delineated in Genesis, is 834 years.
Creation to the flood
Which two men lived such incredibly long lives that they, together, span the entire time from man's creation to the great flood? These two men are Adam (Genesis 5:5) and Methuselah. Adam lived to be 930 and overlapped Methuselah's life by 244 years. Methuselah died in 2313 B.C., the same year God caused the great flood upon the earth.
Where is Abel?
Why is Abel absent in the lineage of Jesus Christ (see Luke 3:38)? After all, He was the second son of Adam and Eve (Genesis 4:1 - 2) whom both Jesus and the Apostle Paul called righteous (Matthew 23:35, Luke 11:51, Hebrews 11:4). The likely reason is that Scripture does not record he produced any children. After his murder, the Bible declares that Adam and Eve produced a third son named Seth, who Luke lists in the physical lineage of our Savior.
The first martyr
Who was the world's first martyr, meaning a person who died due to their faith in God? It was Abel, who was murdered in cold blood by his older brother Cain (Genesis 4:8 - 15). This incident is also the first recorded murder of one human by another found in Scripture.
The firstborn son
The first book of Scripture delineates ten men that represent the first ten generations in the lineage of Jesus (Genesis 5, Luke 3:36 - 38). They are Adam, Seth, Enos, Cainan, Mahalealel, Jared, Enoch, Methuselah, Lamech and Noah. Scripture, except for Adam, states when each of these men produced their firstborn son. The average age when their firstborn came into the world is 158. If we assume Adam was 100 when Cain was born (he was 130 when he produced Seth), then the average age goes down to 152.
One day God asks Cain for the location of his brother. Like a little child, Cain offers a rather terse response to hide his disobedience by feigning ignorance and denying any responsibility on his part. When asked about the whereabouts of Abel, Cain (who was Abel's older brother) states, "I do not know. Am I my brother's keeper [guardian, protector, attendant]?" (Genesis 4:9).
After God discovers Abel has been murdered he decides to punish Cain for his grievous sin. Such an act justly deserves the death penalty (see Genesis 9:5 - 6). God, however, mercifully allows Cain to live but curses any attempts he makes to grow food. He also sentences him to be a wanderer (Genesis 4:12). Cain's self-centered response, which not only lacks any remorse for his sin but also does not acknowledge God's mercy, is "My punishment is greater than I can bear" (verse 13).
