ETYMOLOGY OF YEREVAN/ARARAT, ARMENIAN YEREV-AN, AR-ARAD.

The Armenian language is one of the oldest languages in the world, and is part of the Indo-European family of languages, which includes all Latin, Germanic (including English), Celtic, Indian, Iranian, Slavic, Hellenic languages and others.
Early Christian Armenian chroniclers attributed the origin of the name, “Yerevan,” to a derivation from an expression exclaimed by Noah, in Armenian. While looking in the direction of Yerevan, after the ark had landed on Mount Ararat and the flood waters had receded, Noah is believed to have exclaimed, “Yerevats!” (“it appeared!”). 
As an etymologist, who is not confused by the multitude names for God, I simply divide the word Yerevan into Yerev, which literally translates to "visualize," "view,"  "see" extending to appearance, a vision, an apparition, something coming into view. Taking my lead for the first part.of the name from the early Armenian Christians I take a hard serious look at AN. I find   defining the spirit/of AN is so easy when I go back to Sumerian AN, 3000 B.C. To AN was designated the vault of Heaven, The Sky, heaven". AN was the earliest attested Sky Father/Male deity. In Sumerian religion, he was also "King of the Gods", "Lord of the Constellations, Spirits and Demons", and "Supreme Ruler of the Kingdom of Heaven". So  it seems to me that there is no need to look futher for god. So it seems, whoever it was who established and named YEREVAN, was simply pointing to the location where Yerevan stands today. So Noah must have exclaimed to his followers that he could visualize, see, the site, the location, where heaven, AN, would be founded on Earth. 
I posit that YEREV-AN is the "APPARITION ON EARTH OF HEAVEN, AN. 

In Armenian manuscripts, and scholarly studies which are ongoing, we find that Yerevan was constantly transliterated into many languages. Predominant former spellings of the name of the city were, Erebuni, Erevana, Erevan, Erivan, Erewan, Ervan, Eruan, Arevan, Iravan, Revan, Ayravan etc. Thus the confusion. However I can confirm that all Armenians have knowingly sounded it out as YEREVAN, YEREV-AN. AN himself wandered the highest Heavenly Regions. He was believed to have the power to judge those who had committed crimes, and to have created the stars as soldiers to destroy the wicked. His attribute was the Royal Tiara.
The principal sight, symbol, of Yerevan is Mount Masis/Ararat, which is visible from any area of the capital YEREVAN. The seal of the city is a crowned lion on a pedestal with the inscription “Yerevan.” The lion’s head is turned backwards while it holds a scepter using the right front leg, the attribute of power and royalty. The symbol of eternity is on the breast of the lion with a picture of Ararat in the upper part. The emblem is a rectangular shield with a blue border. Notice the BLUE SKY BORDER.

NANE, extracted from the net, not my words.

Nane (Armenian: Նանե, Nanė) was an Armenian pagan mother goddess. She was the goddess of war and wisdom.

Nane looked like a young beautiful woman in the clothing of a warrior, with spear and shield in hand,^[1] like the Greek Athena, with whom she identified in the Hellenic period.^[2]

She has also been referred to as Hanea, Hanea, Babylonian Nana, Sumerian Nanai or Sumerian NanaiHer cult was closely associated with the cult of the goddess Anahit.

The temple of the goddess Nane was in the town of Thil across from the Lycus River. Her temple was destroyed during the Christianization of Armenia:

"Then they crossed the Lycus River and demolished the temple of Nane, Aramazd's daughter, in the town of Thil."

"Gregory then asked the king for permission to overthrow and destroy the pagan shrines and temples. Trdat readily issued an edict entrusting Gregory with this task, and himself set out from the city to destroy shrines along the highways."

According to some authors, Nane was adopted from the Akkadian goddess Nanaya, from the Phrygian goddess Cybele.

In literary texts, Adad, Enki/Ea, Enlil, Girra, Nanna/Sin, Nergal and Šara all appear as his sons, while goddesses referred to as his daughters include Inana/Ištar, Nanaya, Nidaba, (Haig Nahabeds wife, mother of Ara the beautiful,) Ninisinna, Ninkarrak, Ninmug, Ninnibru, Ninsumun, Nungal and Nusku. An/Anu is also the head of the Annunaki, and created the demons Lamaštu, Asag and the Sebettu. In the epic Erra and Išum, Anu gives the Sebettu to Erra as weapons with which to massacre humans when their noise becomes irritating to him (Tablet I, 38ff).

EXODUS from Sumeria.
When Enlil the god of the atmosphere rose to equal or surpass An in authority, the functions of the two deities came to some extent to overlap. An was also sometimes equated with Amurru, and, in Seleucid Uruk, with Enmešara and Dumuzi. This overlap I believe is the first cause for the fall of Sumer, starting about the year 3000 B.C.

Hydraulic technology of early urban centers: Urartian civilization And the waters returned from off the earth continually and after the end of hundred and fifty days, the waters were abated. And the ark rested in the seventh month, on the seventeenth day of the month upon the mountains of Ararat. - Genesis VIII:4 Urartu (Assyrian) and “ĂUƗUƗt” (Hebrew) is the name of the mountains, where, according to the Genesis 8:4, the Noah’s Aark landed to rest after the great flood. This territory in the Armenian Highlands roughly corresponds to the area between Lakes Van and Urmiah in ancient Armenia (Kyle 1988:955). The history of Urartian Kingdom, referred to as Kingdom of Ararat in many ancient manuscripts, is documented from 1250 B.C. in an Assyrian tablet, which implies a development period of centuries before the manuscript records (Chahin 1987; Mays 2010; Kyle 1988, Garbrecht 1988). The Urartian and Assyrian inscriptions manifest that Urartu was great and powerful kingdom that was able to fight the mighty power of Assyria and prevented its expansion to the North in the period of between 1300 and 600 B.C. (Chahin 1987, Garbrecht 1987). The first King of Urartu was Arame, who gave his name to the Armenians, the successors of Urartians (Garbrecht 1988; Chahin 1987; Kyle 1988; Dyakonov et al 1983). The ancient Armenian civilization is considered as a direct continuation of the Urartian civilization (Dyakonov et al 1983). Urartu was destroyed in 585 B.C. and was replaced by Armenia (Van de Mieroop 2006:205; Kyle 1988:955). The association between the Armenians and the HurroUrartians is comparable with that of the Romans with Etruscans, or Greeks with the Minoans and Pelasgians (Dyakonov et al 1983). As inheritors of Mount Ararat1 and Urartu’s lands, as well we being partially of Hurrian-Urartian racial descent, the claims of Armenians for their homeland to be the Mount Ararat, to which they attach great traditional value, is still valid (Chahin 1987:54) During the most of its history, the territory of Urartian kingdom was located within an approximately triangular area delineated by the three lakes – Van of the west, Urmia on the east and Sevan of the north (Hoffman 1978, Mays 2010).
