Gen 3 23Gen 3 24
A depiction of Eden, Adam and Eve, and the "Garden of Eden" according to Watson Heston (1892).
In religio-mythology, Eden, the “Garden of Eden”, the four rivers of Eden, refers to the mythical location where, according to the Bible, as told in Genesis, god created Adam and Eve, man sinned, and where cast out of the garden.

Eating Knowledge
Gen 2.9 and 2.15-17, wherein we are told about Adam eating from the “tree of knowledge”, and therein becoming “like gods”, and therein knowing “good and evil”, is derived, in part, from the Unas Pyramid Texts (Ѻ), the oldest known Pyramid Texts, the last king of the 5th dynasty (2498-2345BC) – which can be compared to the Teti Pyramid Texts (Ѻ)(Ѻ), the successor to Unas – wherein, according to the Gaston Maspero (1885) translation, cited and commented on by Wallis Budge (1904), who defines it as the "Heliopolitan recension", aka Heliopolis creation myth derivative, in the section titled “Unas: the Slayer and Eater of Gods”, we find the following: [1]

“Unas, it is said, hath eaten the "knowledge,"Saa (knowledge) of every god, and the period of his life and his existence are merged into eternity and everlastingness, which he may pass in any way that pleaseth his spiritual body (sdh), and during this existence he has no need whatsoever to do anything which is distasteful to him. Moreover, the soul[s] and spirits of the gods are in and with Unas, and their souls, and their shadows, and their divine forms are with him.”

Four Rivers (Eden)

Four Rivers
In the four rives section, Genesis 2.10-14, we find reference to "four rivers" or a river going out of Eden with four heads.

In 2004, Ralph Ellis, in his Eden in Egypt, asserted (Ѻ) that the river of Eden, described with four branches is the Nile River, with the Blue Nile and White Nile, being two branches, and two rivers of the Nile Delta being the other two branches. [2] Others (Ѻ), similar to Ellis, have summarized this as follows:

“The Nile starts its flow in the Ethiopian highlands. To many Ethiopians “Gihon” as they call the Nile is one of the four rivers that flowed out of Eden at the beginning of the World. It was the river mentioned in the Bible’s Genesis. In ancient times, powerful Ethiopian kingdoms knew not where the river went exactly, just as the Egyptians knew not where it came from. There even was a great and powerful king named Gihon. The Ethiopians said the river had no resting place.”

The Nile River, in short, is the famed "river" going out of Eden with four heads or branches.

Alternatively, we might see an attempt to morph or syncretize Heliopolis creation myth (3100BC), i.e. the flood myth of the Nile River, whose two major tributaries are the White Nile and Blue Nile, which discharges into the Nile Delta, and Sumerian creation myth (3,400BC), i.e. the flood myth of the Tigris river and Euphrates river, who merge to create the Shatt al-Arab river (Ѻ), which discharges into the Persian Gulf; the gist of this four river, two myth syncretism is summarized as follows:

“The Hebrew redactors used Egyptian myths to make the biblical stories; which, from time to time, had Babylonian myths grafted onto earlier texts or replaced portions of the original stories.”
Gary Greenberg (2000), 101 Myths of the Bible (pg. 7)

Or, as Thomas Paine, in his “Origin of Christianity” (1803), put things, Babylonian mythology was “fixed as a preface to the Bible after the Jews returned from captivity in Babylon”.

“The Bible is not the ‘word of god’, but stolen from pagan sources. Its Eden, Adam and Eve were taken from the Babylonian account; its flood or deluge is but an epitome of some four hundred flood accounts; its Ark and Ararat have their equivalents in a score of deluge myths; even the names of Noah's sons are copies, so also Isaac's sacrifice, Solomon's judgment, and Samson's pillar act; its Moses is fashioned after the Syrian Mises; its laws after Hammurabi's code. Its Messiah is derived from the Egyptian Mandi, Savior, certain verses are verbatim copies of Egyptian scriptures. Between Jesus and the Egyptian Horus, Gerald Massey found 137 similarities, and those between Christ and Krishna run into the hundreds. How then can the Bible be a revelation to the Jews?”
Lloyd Graham (1975), Deceptions and Myths of the Bible (pg. 5)

“In a universe of electrons and selfish genes, blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won’t find any rhyme or reason in it, nor any justice. The universe that we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil, no good, nothing but pitiless indifference.”
Richard Dawkins (1995), River Out of Eden
