Matthew 24:37 - How is Jesus' Presence "Just As" the "Days of Noah"?

At Matthew 24:37, it says:

"For just as the days of Noah were, so the presence of the Son of man will be." NWT

Some have mistaken Jesus' words here to mean that there will be another great Flood that will occur during the Last Days.
 
However, God promised that He would never again destroy all flesh by means of a flood. (Gen. 9:8-11)
 
Therefore, what Jesus was describing here was the apathetic attitude of the world in general as can be further seen in verses 38 and 39:

"For as they were in those days before the flood, eating and drinking, men marrying and women being given in marriage, until the day that Noah entered into the ark; and they took no note until the flood came and swept them all away, so the presence of the Son of man will be."

Also, the conditions before the flood was described in Gen. 6:5,

"Consequently God saw that the badness of man was abundant in the earth and every inclination of the thoughts of his heart was only bad all the time."

So at Matthew 24:37, Jesus was talking about the conditions of what the world would be like before the coming "Great Tribulation". (Matt. 24:21, 22)
