I used google and found "n the Hebrew Bible, Cain and Abel (Hebrew: קין ,הבל, Hevel, Qayin)[1] (Arabic: هابيل قابيل - Hābīl and Qābīl) are two sons of Adam and Eve. The Qur'an mentions the story, calling them the two sons of Adam (Arabic: ابني آدم

.[2]
In the Greek New Testament, Cain is referred to as εκ του πονηρου.[3] In at least one translation this is rendered "from the evil one",[4] while others have "of the evil one."[5] Some interpreters take this to mean that Cain was literally the son of the serpent in the Garden of Eden. A parallel idea can be found in Jewish tradition,[6] that the serpent (Hebrew nahash נחש

from the Garden of Eden was father to Cain.
In all versions, Cain is a crop farmer and his younger brother Abel is a shepherd.[7] Cain is portrayed as sinful, committing the first murder by killing his brother,[8] after God[9] has rejected his offerings of produce but accepted the animal sacrifices brought by Abel.[10] Accordingly, Abel was the first human to ever die. Cain is mentioned as Adam and Eve's first child; thus, Cain, according to Scripture, was the first human ever born.
The oldest known copy of the Biblical narration is from the 1st century Dead Sea Scrolls.[11][12] Cain and Abel also appear in a number of other texts,[13] and the story is the subject of various interpretations.[14] Abel, the first murder victim, is sometimes seen as the first martyr;[15] while Cain, the first murderer, is sometimes seen as an ancestor of evil.[16] A few scholars suggest the pericope may have been based on a Sumerian story representing the conflict between nomadic shepherds and settled farmers.[17] Others think that it may refer to the days in which agriculture began to replace the ways of the hunter-gatherer.[18] [19]
Allusions to Cain and Abel as an archetype of fratricide persist in numerous references and retellings, through medieval art and Shakespearean works up to present day fiction."
