Claim CH135.1:
The Bible, remarkably for its time, notes that the eighth day after birth
is the safest time to perform circumcisions (Gen. 17:12; Lev. 12:2-3).
When a baby is born, they have no bacteria in their intestines for the
first few days.  By the seventh day, the bacteria multiply and produce
vitamin K.  Without vitamin K and prothrombin protein (which is produced
by the liver using vitamin K), the blood will not clot properly and the
possibility of severe bleeding as well as infection would make
circumcision dangerous in a primitive medical situation.

Response:
-  Although the danger of severe bleeding is worst in the first week, it
   can occur any time in the first month (Zipursky 1999).  According to
   most medical experts, the best time for circumcision is never (Ritter
   and Denniston 1996).  The procedure is medically unnecessary at best.
   The procedure is painful, and there is some evidence that pain in early
   infancy makes one more sensitive to pain throughout life (Ruda et al.
   2000).
 
 
-  Attributing a requirement of some special knowledge for this insight
   assumes the ancient Hebrews were stupid.  Classic hemorrhagic disease
   of the newborn is usually seen on days two through five (Zipursky
   1999); it would not take a lot of observation and thought to conclude
   that it would be best to wait until the worst danger is over.
 
 The Susus near Timbuctoo and the Guemos of South America are also said
   to perform the rite on the eighth day (Hirsch et al. n.d.).
