Archaeologists have been left wondering what the purpose of the objects was and how such an ancient culture, at the very beginning of Chinese civilization, could be so advanced.

Of course, we Christians believe these were most likely fallen angels- and there is precedent for supernatural beings visiting Earth and mingling with mankind, i.e. Genesis 6:4 and the Book of Enoch (which is not part of the Bible but was referenced in scripture- and we know that Enoch was a man of God).
