The Status of Zeus in Bible

Have you ever asked,
If only one God means virgin God,supposed Jesus is God,but, why were there so many adultery gods in Greek Myth?What was the legend god's status in Christian idea?

In the Book of Genesis 6:2
"The sons of God saw the daughters of man were attrative ,and they took as their wives any they chose."

In Catholic version ,it used "giants",as God's sons.And this was very much connected with Greek Myth!

However,we Chinese were another story!We combine with God,but,we don't believe that God is a visible image!
