Question: Ask The Nuwaupians: Is Nibiru Really a Sumerian Word as York Claimed?

Answer: They won't even have a clue.

I was reading up on a related story, and I came across a section from one of York's books mentioning Nibiru. It inspired me to put this short question to the clueless Nuwaupians.  I mention that they wouldn't have a clue because for one; York never showed a Sumerian inscription where Nibiru can be found, nor demonstrated any ability to read or write the Sumerian language.  This bogus claim by York and his ignorance has been around since he started spreading Zacharia Sitchin's nonsense in 1992 to us.  In his book, the so-called El's Holy Torah York claims that the "mighty ones", some "beings" came from a "Mothership" called "NIBIRU".  However, York never cites a single Sumerian primary source where the claim can be verified.  In fact, of all the books York is said to have written, NEVER has he ever shown Nibiru to have been a Sumerian word. 

So I ask (again), where's the evidence of Nibiru being a Sumerian word?
