RAMADAN: Why was Afghanistan always messed up?

Afghanistan was inhabited by the Aryan tribes and controlled by the Medes until about 500 BC when Darius the Great (Darius I) marched with his Persian army to make it part of the Zoroastrian Achaemenid Empire. In 330 BC, Alexander the Great (Alexander III of Macedon) invaded the land after defeating Darius III of Persia in the Battle of Gaugamela and Afghanistan became part of the new Greco-Bactrian kingdom. Alexander the Great and his army were gay. They introduced ity in Afghanistan. Now it is part of Afghani Culture. Majority of Afghan population is illiterate and gay.
