Agree. If God punished the angels that sinned by having relations with the daughters of men, how could He not punish the sons of men that attempted to have relations with the sons of God?
Genesis 6 and the days of Noah have relevance today.
Precisely. And these weren’t the “Righteous sons of Seth”. First, the Bible doesn’t say that, and second, if having sex with the daughters of men was frowned upon, how were they “righteous?” Text doesn’t support it at all.
Text doesn't say that.
