Jesus said the coming of the Son of Man will be like the days of whom?

Answer: Noah

As before the flood people ate, drank and married until Noah entered the ark, so it will be at the Son of Man's coming.

“As it was in the days of Noah, so will it 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 were oblivious until the flood came and swept them all away. So will it be at the coming of the Son of Man.”— Matthew 24:37-39 (BSB)
