As Ham’s descendants after the flood moved southward from Ararat toward Africa, some improperly settled in the Near East. To oust them, God gives their lands to Abrahamic tribes, beginning with Moabite and Ammonite descendants of Lot, and then to the Israelites.

There is no indication that all giants were ever eradicated, but rather that the number of them appearing in the Hammite population eventually waned as the population normalized over time. Perhaps a similarity can be drawn from the way super-longevity in humans also attenuated in the generations after the flood. For example, in David’s time there was “an Egyptian, a man of great stature, five cubits high” 1 Chronicles 11:23, which is about 7.5 feet tall, and there was Goliath who was almost 9 feet tall (1 Sam. 17:23). But these giants were both small compared to Og who lived 500 years earlier, who was over 13 feet tall (Deut. 3:11). This would suggest that giantism was most notable in Ham’s first generations, but that the expression of it declined steadily over time.

Since Noah had pure genetics (Genesis 6:9), the only way for giantism to have survived the flood and made its reappearance among Ham’s descendants would be if Ham’s mother and/or his wife were genetic carriers for it.

It is conceded that Ham was Noah’s true son, but that does not mean he had the same mother as Shem and Japheth. In fact, the disgraceful way Ham treated his father’s nakedness demonstrates that Noah’s wife was not his mother, but rather the mother of the other two sons who showed her respect. Ham’s black descendants are entirely foreign from both Caucasians and Orientals, which two races by comparison have slight differences between them. In fact, since triplets are unlikely, yet Noah had all three sons in the same year of his life (Genesis 5:32), it is all but certain that Ham was born of a different mother.

This means a Negro concubine of Noah contaminated her son Ham with giantism. Alternatively, Ham took a Negro wife and she was the source of the contamination. Or perhaps, it was both.

The fact that giantism is a human carried genetic trait makes it much less fantastic and otherworldly than the UFO sensationalism would suggest.
