If it weren't so slow in here I probably would have been content just to kick back and observe. :-)
It says, There were giants in the earth in those days, but it does not say they are the offspring of the sons of God and the daughters of men. It does say this about the offspring: the same became mighty men which were of old, men of renown. These were not monstrosities; they were men. The record here makes it very clear that the giants were in the earth before this took place, and it simply means that these offspring were outstanding individuals.
What do ya think?
