Ancient Armenia was a rocky land of ravines, rivers, rugged cliffs, and hundreds of stone monuments and churches. Many survive to this day inside the Turkish border near Armenia. Armenia anciently had far more bigger land than it has now.
De Morgan has said there are signs which show that the Armenians, as their other Aryan relatives, were nature worshipers and that this faith in time was later changed to the worship of national gods, of which many were the equivalents of the gods in the Roman, Greek and Persian cultures. The main proto-Armenian (Aryan) god was Ar, the god of Sun, Fire and Revival. The Armenian hypothesis of Indo-European origins connects the name with the Ar- Armenian root meaning light, sun, fire found in Arev (Sun), Arpi (Light of heaven), Ararich (God or Creator), Ararat (place of Arar), Aryan, Arta etc. According to the researchers, the name of Ardini religious center of ancient Urartu also related to the god Ar-Arda. The cult of Ar appear in Armenian Highland during 5-3th millennium BC and had common Indo-European recognition: Ares (Greek), Ahuramazd (Persian) Ertag (German), Ram (Indian), Yar-Yarilo (Slavonic) etc. After adoption of Christianity the cult of Ar was also evident in Armenia, remembered in the national myth, poetry, art and architecture.
The territory of the Armenian language appears to have been roughly coincidental with Hurrian and closely related Urartian (with Dark shading). The poorly known and presumably related non-Indo-European Etio language was to its north. Many of these languages occupied partially or wholly the earlier territory of the Kuro-Araxes culture (light shading). The nearest Indo-European-speaking neighbors of the Armenians were the Gutians and Hittites (including the Luvians and Palaic-speaking peoples), none of which spoke languages closely related to Armenian. Assyrian was a non-Indo-European language. Burials with wheeled vehicles have been uncovered at Trialeti and Lchashen.
