The artifacts of many places including Egypt are many times more ancient than 12,900 years old. Many were built way prior to that date when the comet or bolide came into our realms. The planet was almost wiped clean via tsunamis that were over a mile high. To have survived this catharsis humanity had to see it coming, and some apparently did. Our planet was highly advanced then and we had gone to and from Mars, Venus, the other realms. We are the survivors now and have forgotten who and what we were. It is time we realized our past.
