Let me suggest a distinction I think is being missed here. It is true that
the laws against incestuous relations were written down during Moses time,
but that does not mean that they weren't in effect earlier. The law against
murder was also written at that time, but that does not mean that murder was
therefore OK prior to Moses. God took a dim view of Cain's slaying of Abel.
By the logic of the above, one would conclude that like incest, murder was
not forbidden before Moses and neither was stealing, adultery or anything else.

As a former YEC (of which I am less proud), I had some discussions with Jody
Dillow about this issue years ago. When he came out with his book, The
Waters Above, p. 170, he wrote,

"Experiments have bee conducted in which mice were placed hundreds of feet
below the ground to shield them from all cosmic radiation. There was no
idnication of an increase in longevity in either the parents or their
"So it appears that canopy theorists have been in error when they
appealed to the shielding effect of the canopy as a direct explanation for
antediluvian longevity."

On page 169 he wrote:

"Many studies have been performed on mice to determine the effects of X-rays
and gamma radiation on longevity. However present evidence suggests a
shortening of human life of 11% per 1,000 rads for an entire lifetime.
Since Table 5.5 indicates that the average dosage a man receives is only 12
rads in a lifetime (0.192 rad/yr x 67 yrs), we can see that present
radiation levels have no effect on reduced longevity."

If this is so, then I would expect people in Denver to live shorter, less
rewarding lives than people in Houston. there is less atmospheric shielding
in Denver or even Golden, Colorado. but this does not seem to be significant.

Dillow further writes:

"Furthermore, these studies involve bombardment with X-rays and, even
without a canopy, no X-rays reach the surface of the earth. Only visible
and some ultraviolet and infrared radiation reaches the surface in any
appreciable amount. Ultraviolet radiation will not penetrate deeply below
the skin. So while it is probable that somatic mutations have an effect on
the aging process, it seems fairly well established that cosmic radiation
contributes only in a minor way to somatic mutation." p. 169-170

Thus, the radiation we have on earth does not cause germ cell mutation in
any appreciable quantities.
