We Iranians do not have 8000 years of Iranian history. That is rather too generous. Those bits of artifacts and archeological sites that do date to 8000 years ago are pre-Elamite and Elam and Susiana were themselves not not an Iranian people. Iran is not a geographic construct: it is (and remains in the current diaspora), true to its nomadic Aryan roots, a portable civilization of mind, heart, and spirit. Proto-Iranians date to 2nd millenium B.C. The Medes were the first Iranian urban civilization in the Iranian Plateau and they date to 3000 years ago. The Pars ("Persians") - a related Iranian tribe (Achaemenid Shahanshah Cyrus's grandfather was the king of the Medes) - followed. Subsequent to Alexander, there was a period of Greek occupation, followed by 2 lesser known, but actually culturally more influential than Achaemenids, Iranian empires: the Parthians and the hugely influential Sassanian.
