I hold multiple views on creation. My My personal view under the assumption that human evolution occurred in a Darwinian manner descendantdescending from apes is that humanity existed in a non-image of God state (no spirit) prior to Adam and Eve. There There is some Biblical support for this. Genesis Genesis 4:13 indicates that when Cain was sent away, he indicates that whoever finds him will kill him, but who else was there? Further Further, it says in verse 26 of that chapter that at that time people began to call on the Lord. Then Then in chapter 6, verse 1 indicates that the sons of God saw that the daughters of humans were beautiful and they married any of them they chose.
It is possible that there was a more animalistic version of humanity thatwhich the descendants of Adam and Eve interbred with, and that Adam and Eve were the introduction of a human spirit in the image of God rather than the simple flesh and blood creature. Then, Then with the Floodflood, only those who had bred into the descendants of Adam and Eve would have remained, since Noah was part of that line.
Ultimately, since Genesis makes no attempt to be a history book, it leaves a lot of questions unanswered, so it's really all just theories based on fragments of information and particular phrasings that may or may not be valid interpretation. Thus Thus I give this theory with the caveat that it should be taken with a large grain of salt and regarded as just that. A A theory.
