Wow, just reading thru this thread clearly shows why ANY advanced intelligence would be hesitant to say the lest, to initiate open contact with us. In the few instances where some attempted to present some sort of viable answers to these questions put forth, the majority of the responses were extremely negative, and some were downright vile! For anyone who is sincerely seeking truth, it is out in the open for those who have eyes,and ears. I think Ningishzidda made sure of this, as directed by his father Enki. Truth does not have to be argued. Our world is on the brink of change, this is obvious if we look at the increase in technology, and the parallel increase in violence and destruction, and general lack of love for the fellow man. No one can be wrong, no one wants to say "I don't know".
I have read the Sitchin series, I have read the Emerald Tablets of Thoth, and the Divine Pymander of Hermes. The one theme I found common to all was a genuine desire by the authors to impart a teaching of fellowship, kinship, and love for our Humanity upon the reader. We have the Staff of Hermes (Thoth , Ningishzidda, Kulkun etc) as the sign for medicine and well-being. Research the origins of this sign.
It in itself is a guide for the development of the latent powers that exist inside man, as a direct inheritance from our Ancient Ancestors. If we were to re-awaken even a tiny portion of theses gifts, there would be no need to question, argue, insult, or debate truth. How can a true search for knowledge be de-based in such a way that it becomes insults, and unneeded hostility towards someone else's interpretation or view? This is Civilization? Let us ALL destroy some barriers of our own creation, and allow some semblance of truth to come in thru the cracks so we may one day get a glimpse of TRUE knowledge, wisdom, and understanding.
