With this kind of discovery it adds to theories that ancient civilizations were influenced by aliens from another world. If not that then it at least proves that the ancient Egyptians were more scientifically minded than we thought them to be. Either way it is a very interesting discovery and one that definitely gets the imagination working over time.
The discovery of meteorite iron in King Tut's tomb changes history as we know it. It is yet another example of the many mysteries of the ancient world that we continue to discover. The more we learn about the Ancient Egyptians, the more we realize how little we truly understand about their civilization and culture.
The discovery of meteorite iron in King Tut's tomb does not change history. Why would it? The reality is that, but for a few egghead archeologists and 50 year old people that still live in their parents' basement, no one really cares if Tut's wares were made of iron, rock or mud.
The discovery of meteorite iron in King Tut's tomb doesn't seem all that unusual to me. Meteorites have been hitting the earth for as long as it's been a solid hunk of rock floating through space. There is already so much that we don't know about the Egyptian history that it wouldn't be surprising to find out that this ancient (and inventive) society was capable of working down meteorite iron. There were already master workers of stone and precious metals. AND, if you look at the history of gold on our world, you'll see that part of that gold came to the earth surface by.... wait for it.... meteors! As for changing history, I don't believe that history is ever changed, per se. Rather it is amended, expanded and annotated with each new discovery.
