The giants of the Bible were tall and functional, some were capable of being warriors on a battlefield. Some of them had six fingers and six toes but we don't know if this was a common trait, the accounts of Og and Goliath don't mention this and both men's corpses were available for inspection on the battlefield. There are people today who have six fingers and six toes without displaying any other aberrational traits.
What the Bible does not discuss is people born with severely elongated skulls. Such skulls are found in the hundreds in Peru and scientists claim that they were compressed since childhood to create a special race, rather than born as a special race. Investigators claim that the volume of the skulls is sometimes larger than the volume of a normal human skull but none of the skulls are given as having a larger volume than the normal range for human skulls, 950-1800 cubic centimeters. One skull was sent for DNA testing which was done by someone who believes they are extraterrestrials to begin with and not by neutral researchers. Before the DNA testing was completed they concluded that it had to be an extraterrestrial and I can't find anything about the DNA testing having been completed during the couple of years that have passed since then. There was another skull called "the star child" that investigators made similar claims about but an other site claims that thorough DNA testing was done on that one many years ago which confirmed that it was a deformed human being.
Since these elongated skulls have been mentioned in the giants threads as evidence of Nephilim (not the same as an extraterrestrial), I would like an update on that. What have they got ?
