Author's Note: "Then the Lord said to Noah, ‘Go build an ark, you and all your household, for I have seen that you alone are righteous before me in this generation... For I will send rain on the earth for forty days and forty nights; and every living thing that I have made I will blot out from the face of the ground!"
And Noah built an ark as the Lord had commanded him.
I figure that everyone else focused on the spider : )
