+Nightshift10000 Actually it is very similar if you have a closer look at the letters. First research to this topic only led to the information that some people think John Dee himself might have written the Voynich Manuscript... far too little information in my opinion
+Hybrid Librarian Maybe they really were here but then they left. And then a cataclysmic event occured and they got erradicated. There own planet all deserted and alone somewhere in space. If they left some traces and DNA after themselves maybe thats all there is left.
