let's revisit Matthew 24

But as the days of Noah were, so shall also the coming of the Son of man be.

For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark,

And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.

Then shall two be in the field; the one shall be taken, and the other left.

Two women shall be grinding at the mill; the one shall be taken, and the other left.
