Genesis 19:31

I'm talking today about Lot and his two daughters after they leave Sodom and Gomorrah and it's been destroyed (without Lot's wife of course... she didn't listen).  They go up to some mountain because they feared a place they went to first called Zoar... for some reason Lot and his two daughters take refuge in a cave.  Now they believe the world has come to an end because of the massive destruction that had just taken place (I'm assuming here).

31 And the first-born said unto the younger, Our father is old, and there is not a man in the earth to come in unto us after the manner of all the earth: 32 come, let us make our father drink wine, and we will lie with him, that we may preserve seed of our father. 33 And they made their father drink wine that night: and the first-born went in, and lay with her father; and he knew not when she lay down, nor when she arose.

Wow! That's intense, I'ld say this is a definate what NOT to do.  Now I realize they were living in a cave, but that was because Lot had some issue with Zoar and decided to live in this cave.  It was a different time and maybe the men would have killed Lot for his daughters... but how could a daughter, much less both sleep with their own father?

34 And it came to pass on the morrow, that the first-born said unto the younger, Behold, I lay yesternight with my father: let us make him drink wine this night also; and go thou in, and lie with him, that we may preserve seed of our father. 35 And they made their father drink wine that night also: and the youger arose and lay with him; and he knew not when she lay down, nor when she arose. 36 Thus were both the daughters of Lot with child by their father.

So you get your younger sister to do the same thing to "preserve seed of our father"?  As well supposedly Lot never remembers any of this.  Also, notice he's made to drink wine that makes him forget, that's for all you christians out there that think wine in the bible wasn't fermented.... well it was.  Lot seems to forget everything from both these nights. And even after all this and his two daughters become pregnant Lot never questions why his daughters are pregnant.  Every father knows that even if you only have a sheep herder's stick you're going to go find out who has been in your hen house (a bit of an example of the modern day father with a shotgun).  Each of his daughters bare a son Moab and Ben-ammi.  Poor little mongoloids.
