It has been a 120 years since the beginning. If it is the truth that the days of man in the flesh on earth shall be 120 years then it is not a lie when it records that men lived older than 120 years. It is simply a choice one makes whether to believe the word that proceedeth out of the mouth of the LORD or to lean to their own understanding.
In fact it could be true, that men lived longer than 120 years but not in the flesh on earth. I know, what a radical ideal of life after the end of the animated flesh.
Yet, it is written that after men began to multiple upon the face of the earth, that those men who were born not of blood or flesh, nor the will of man but of God, took unto themselves the daughters of men that were born unto them to be their wives, that the LORD revealed that his word was not going always to strive with man, yet his days in the flesh on earth would 120 years.
The scriptures also clearly establish that what was said by the LORD told before the daughters of men gave birth to the children. Since the days of Noah were some 1600 years after the beginning of man on the earth, it would have been longer than 120 years after the days of the men of renown were born.
