Read what Jesus said, in Luke 17, regarding THE nature of events. It is Jesus Who cites the days of Noah and Lot. What do those two events have in common? ... The ‘righteous’ are removed BEFORE the wrath happens.
Luke 17:24 Because just as lightning flashes and shines from one end of the sky to the other, [Lightening in the clouds, not striking the earth] so will the Son of Man be in his time. 25 But first he must suffer a great deal and be rejected by those living today. [The crucifixion]26“Just as it was in Noah’s time, so it will be in the days of the Son of Man. 27 People were eating, drinking, marrying, and being given in marriage right up to the day when Noah went into the ark. Then the flood came and destroyed all of them. 28 So it was in the days of Lot. People were eating and drinking, buying and selling, planting and building. 29 But on the day when Lot left Sodom, fire and sulfur rained down from heaven and destroyed all of them. 30 The day when the Son of Man is revealed will be like that.
We've all seen lightening up across the clouds, not striking the ground.
The common thing about the Noah account and the Lot account is the removing of the righteous BEFORE the catastrophe is loosed.
The DAYS of the Son of Man will be ushered in like lightening flashing across the sky from Eastern Horizon to Western Horizon. The DAY the lightening flashes starts the DAYS of the Son of Man. The Son of Man is a term understood by the Jewish people of that epoch.
