It wasn't a bible story. It's religious theory based on a line in Genesis about giants. 
 According to religious theory, the world was populated by giants or fallen angels, and over time humans and them began interbreeding...because why the fuck not?
And then God got pissed that his creation was now some Cronenberg hybrid, so he found the one guy who was still competely pure of human blood, got him to build an ark, throw some animals on board, and he drowned those freaks.
The End.

Either way, it gives a deep truth about the nature of the aforementioned beings.
That despite their hatred for us, yet they are obsessed, and deeply jealous because they know that God has done a good thing for us unlike them.
