A major astronomical event provides a partial explanation for how God may have acted to reduce the long pre-Flood human life spans. Cosmic radiation is one of the main factors that limits human life expectancy. The cosmic radiation coming down to Earth has not been uniform through time, and in fact, most of the deadliest cosmic radiation Earth experiences comes from a fairly recent and nearby (1300 light years away) event, the Vela supernova (A supernova is a rare celestial phenomenon, the explosion of most of the material in a star). About 20,000 to 30,000 years ago (roughly the time of the Genesis flood), the Vela supernova erupted.39, 40
Prior to the Vela supernova, only a fraction of the current level of deadly cosmic radiation bathed the Earth. Under these lower radiation conditions (coupled with complementary biochemical adjustments) life spans of up to 900 years might have been possible. Scientists do acknowledge that this higher-level radiation silently bombarding the Earth since Vela plays a significant role in limiting life expectancy. Moreover, a significant radiation event such as Vela would explain the mathematical curve, the gradual, exponential reduction in life spans, from about 900 to 120 years reported in Genesis 11.
Assessing Scientific Plausibility
Advances in the biology and biochemistry of aging have been remarkable, and, at the same time, they reveal that the aging process is, indeed, complex. Much remains to be learned and discovered about it. Recent discoveries do clearly indicate, however, that aging can result from subtle changes in the invisible realm of cosmic radiation and cellular chemistry. Given the subtly of these changes, investigators are gaining some hope and confidence that in the near future they will be able to slow the human aging process through drug treatment and dietary alteration.
Scientists' success in altering the life span of selected organisms (such as worms, yeast, and fruit flies) and their emerging ability to increase human life expectancy through biochemical manipulation lend scientific plausibility to the long life spans recorded in Genesis 5. If humans with their limited knowledge and power can alter life spans, how much more so can God? He could have used any of four (or more) subtle alterations in human biochemistry to allow for long life spans. He could have used the Vela supernova or other astronomical events, in combination with complementary biochemical changes, to shorten human longevity.
Exactly how God altered human life spans no one knows. However, recent discoveries in the biochemistry of aging continue to build the case for the reliability of Scriptureeven of Genesis 5 and 6. Researchers stand on the threshold of additional breakthroughs in understanding the aging process. Further advances are anticipated in the endocrinology and hormonal control of aging, and in deciphering Werner's syndrome (a disorder that leads to premature aging).41, 42, 43, 44 One can look forward to these and other discoveries in the biochemistry of aging with the confidence that they will continue to lend credibility to the biblical record.
Not that you'll read that, or understand it if you do, but here are a few biochemists that
do:
Fazale R. Rana, Ph.D.
Hugh Ross, Ph.D.
Richard Deem, M. S.
And I can't add to or take away from the Bible. So:
Gen. 1:6,7
2 Pete 3:5
Gen. 2:5-6
Now no shrub had yet appeared on the earth and no plant had yet sprung up, for the Lord God had not sent rain on the earth and there was no one to work the ground, 6 but streams came up from the earth and watered the whole surface of the ground.
But there went up a mist from the earth, and watered the whole face of the ground.
If you are going to argue the Bible, you gotta read it Jake.
