Reading Genesis, there seem to be quite a few references to some 'other' humans. How do scholars interpret those passages (and more importantly, why do they interpret them a certain way)? Are Biblical scholars sure Adam and Eve were the first humans?
In Genesis 1:26-29 it is first described how God created man and woman, without giving specific details: no mention of them being named Adam or Eve, for example, or if there were only two humans that he created.
Genesis 2 starts by describing the seventh day, which suggests the events are a continuation of those in Genesis 1. However, Genesis 2:4-7 describes how the plants were not growing because there was no man to work the ground, which suggests that Genesis 2 is a retelling in greater detail of the events in Genesis 1.
However, that to me is unclear if it's a right interpretation since the events are described in a different order.
In Genesis 4:14, Cain fears that if he leaves the presence of God, "whoever" finds him will kill him. Who?
Genesis 4:17-18 lists descendants of Cain. Now, Cain might have had kids with his own mother, but it's interesting to note that all named descendants are male. In Genesis 4:19, Lameh (the last descendant of Cain) is said to marry two wives: Ada and Zillah. Where did these come from? Are the the descendants of Cain as well? Why are they not mentioned in Genesis 4:17-18, then?
And one last interesting bit, Genesis 6:2 mentions how the "sons of God" found the "daughters of humans" attractive. Who are the sons of God? Who are the daughters of humans? Why the distinction? My own uneducated interpretation would be that the 'sons of God' are the descendants of Adam and Eve, while the 'humans' are the others.
