Was King Tutankhamun alive before Moses' pharaohs?

Yes, King Tutankhamun lived before the time of Moses' pharaohs. Tutankhamun reigned during the 18th Dynasty of ancient Egypt, around 1332-1323 BCE. In contrast, the biblical account of Moses is generally placed later, during the Exodus period, which is often dated to the 13th century BCE. Thus, Tutankhamun's reign predates the pharaohs associated with Moses.
