What Were the Days of Noah?

What were the days of Noah?!!!
What were the days of Noah?!!! As it was in the days of Noah, so it will be at the coming of the Son of Man. For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man. Matthew 24:37-40 (NIV)
