Comet 67P Cannot Be Primordial.

Red arrow points to an object that measures about 40 X 40 X 4 meters. It is shaped like a block sitting on Comet 67P. It cannot be primordial (existing in or persisting from the beginning (as of a solar system or universe)), because no mechanisms of the comet could have produced the block. It is not an UFO. It looks like concrete foundation often found on “ridges” in Gale Crater, Mars. Four red boxes contain structures often found on Mars.
