Christian extracanonical work found in Ge'ez
The Conflict of Adam and Eve with Satan (also known as The Book of Adam and Eve) is a 6th-century Christian extracanonical work found in Ge'ez, translated from an Arabic original.
It does not form part of the canon of any church.
Books 1 and 2 begin immediately after the expulsion from the Garden of Eden, and end with the testament and translation of Enoch. Great emphasis is placed in Book 1 on Adam's sorrow and helplessness in the world outside the garden.
In Book 1, the punished Serpent attempts to kill Adam and Eve, but is prevented by God, who again punishes the Serpent by rendering it mute and casting it to India. Satan also attempts to deceive and kill Adam and Eve several times. In one of his attempts on their life, he throws a boulder which ends up encompassing Adam and Eve. God eventually saves them and compares this event with the upcoming Resurrection of Christ. God also predicts several other future Biblical events, including Noah and the flood.
In Book 2, the "sons of God" who appear in Genesis 6:2 are identified as the children of Seth, and the "daughters of men" as women descended from Cain, who successfully tempt most of the Sethites to come down from their mountain and join the Cainites in the valley below, under the instigation of Genun, son of Lamech. This Genun, as the inventor of musical instruments, seems to correspond to the Biblical Jubal; however he also invents weapons of war. The Cainites, descended from Cain the first murderer, are described as exceedingly wicked, being prone to commit murder and incest. After seducing the Sethites, their offspring become the Nephilim, the "mighty men" of Gen. 6 who are all destroyed in the deluge, as also detailed in other works such as I Enoch and Jubilees.
Contradiction with the Bible
1st Adam and Eve LXXVIII:16[10] says "Then on the morrow Adam said unto Cain his son, 'Take of thy sheep, young and good,
and offer them up unto thy God; and I will speak to thy brother, to make unto his God an offering of corn.'"
By contrast Genesis 4:2–3 says "And in process of time it came to pass, that Cain brought of the fruit of
the ground an offering unto the LORD. And Abel, he also brought of the firstlings of his flock and of the fat
thereof. And the LORD had respect unto Abel and to his offering".
Book 2 has discrepancies with Old Testament saint lifetimes:
Enos lived 985 years (2nd Adam and Eve XIV:4[11])
whereas the Bible says that he lived 905 years (Genesis 5:11).
Mahalaleel lived 870 years (2nd Adam and Eve XVI:2[12])
whereas the Bible says that he lived 895 years (Genesis 5:17).
Jared lived 989 years (2nd Adam and Eve XXI:13[13])
whereas the Bible says that he lived 962 years (Genesis 5:20).
