Genesis 3

[abaris]

I think the "us" is reference to the trinity and if you read beyond the first book the is a great deal of talk about enternal life

Yeah, multiple personality disorder.

Also, the concept of trinity is far from original.

Egypt’s history is similar to Sumeria’s in antiquity. In his Egyptian Myths, George Hart, lecturer for the British Museum and professor of ancient Egyptian heiroglyphics at the University of London, shows how Egypt also believed in a ‘transcendental, above creation, and preexisting’ one, the god Amun. Amun was really three gods in one. Re was his face, Ptah his body, and Amun his hidden identity (24). The well-known historian Will Durant concurs that Ra, Amon, and Ptah were ‘combined as three embodiments or aspects of one supreme and triune deity’ (Oriental Heritage 201). Additionally, a hymn to Amun written in the 14th century BC defines the Egyptian trinity: ‘All Gods are three: Amun, Re, Ptah; they have no equal. His name is hidden as Amun, he is Re... before [men], and his body is Ptah’ (Hornung 219).

That's only one preexisting trinity in the region where jews adopted Yahweh. Also, when we're talking Genesis and the belief of the jews, we're not even at trinity's door. The jewish belief doesn't accept the trinity.

In contrast, Judaism is strongly monotheistic with no hint of a trinity. The Hebrew Bible (the Old Testament) is filled with scriptures such as ‘before Me there was no God formed, Neither shall any be after Me’ (#Isa 43:10 qtd. in Isaiah), and ‘there is no other God...I am the Lord and there is none else’ (#Isa 45:14,18 qtd. in Isaiah). A Jewish commentary affirms that ‘[no] other gods exist, for to declare this would be blasphemous...’ (Chumash 458). Even though ‘Word,’ ‘Spirit,’ ‘Presence,’ and ‘Wisdom’ are used as personifications of God, Biblical scholars agree that the Trinity is neither mentioned nor intended by the authors of the Old Testament (Lonergan 130; Fortman xv; Burns 2).

That concept only came up with christianity and was again influenced by Greek and Roman culture.

These were not the only trinities early Christians were exposed to. The historical lecturer, Jesse Benedict Carter, tells us of the Etruscans. As they slowly passed from Babylon through Greece and went on to Rome (16-19), they brought with them their trinity of Tinia, Uni, and Menerva. This trinity was a ‘new idea to the Romans,’ and yet it became so ‘typical of Rome’ that it quickly spread throughout Italy (26). Even the names of the Roman trinity: Jupiter, Juno, and Minerva, reflect the ancestry. That Christianity was not ashamed to borrow from pagan culture is amply shown by Durant: ‘Christianity did not destroy paganism; it adopted it’ (Caesar 595).
