End of the world

Here is the situation.

You and your daughter are the only humans left on the planet.
What do you do?

i wud have sex with her, then have kids until i have at least one boy and one girl, maybe more. then, they will marry, have boy and girl, then they will cross marry by cousins, then contoinue, wit second cousins, and so on until it has no side efects, and repopulate basically. totally man, life is about survival. and it's better than just giving up humans cuz that's like a waste, it's like nothing.
