Just Another Tomb

Has anyone considered that when Holloway says "Just another tomb" in front of the door with the Deacon mural, that he is referencing back to failed archeological digs that perhaps him and Shaw managed on Earth trying to find more star map evidence? Maybe that line is not really a literal reference to the room behind the mural door or urn chamber, but just a statement of disappointment by Holloway that they just traveled all that way to find another empty room with no answers and no one to answer their questions. Finding that room was just like finding the cave paintings that only lead to more questions. In that context, the Deacon mural on the door could perhaps be like the star map paintings back on Earth that symbolize an origin of some sort and that could be the intended dual ambguity of that line.
