David in Psalms, Peter in his epistles, Isaiah, Jeremiah ALL speak about a people before Adam whom Satan [when he was on our side/God's side/ why he is known as Light Bringer] was mediator of between them and God [like Christ is with us].
There is a Luciferian theory. And it begins in Genesis 1:1 when it claims the heavens and the earth was finished (this means completed with life).
Of course, verse 2 we see God above the face of the deep/waters. This is to some a reference of a flood before Noah's flood. One that wiped everyone off the face of the earth [some elude this also to the ICE AGE after the waters melted].
And of course, the question always remained...if Adam was the first ever man created...HOW DID CAIN find a wife from another sect of People? In this part of Genesis story, we have Adam, Eve, Abel, and Cain. But yet, after he kills Abel, there is more people and people who had a daughter whom Cain married!!
My theory is Adam was not the first ever man created...BUT, he was the first man created in the lineage of Christ. Because the Tree of Life in the Garden is a representation of Christ, like all throughout the Bible we have representations of Christ before Christ was here. Example: The Holy of Hollies and the Ark of Covenant with the Mercy seat (EVER NOTICE THE 2 ANGELS ON TOP OF MERCY SEAT ARE PLAYED OUT DURING THE RESURRECTION OF CHRIST [with 1 angel at the head of where Christ was laid and another angel at the feet with both facing one another = MERCY SEAT])...
The scriptures are fascinating!!
I agree with Preacher4Truth about most of the above. This is the kind of conjecture that happens when you consider the opening Chapters of Genesis to be a lie/myth, as well whenever you attempt to combine what the Bible teaches us about Creation on the one hand, with the various hypotheses that atheistic science has come up with as an alternative/to contradict what the Bible says about our origins on the other.
As for the wife of Cain, here is the explanation about that (remembering, of course, that familiar ties were necessarily close back then).
.........Genesis 5
.........1 This is the book of the generations of Adam. In the day when God created man, He made him in the likeness of God.
.........2 He created them male and female, and He blessed them and named them Man in the day when they were created.
.........3 When Adam had lived one hundred and thirty years, he became the father of a son in his own likeness, according to
.........his image, and named him Seth
*.
.........4 Then
the days of Adam after he became the father of Seth were eight hundred years,
and he had other sons and daughters.
.........5 So all the days that Adam lived were nine hundred and thirty years, and he died.
*(Our progenitors, no doubt, had other sons and daughters prior to Seth's birth, IOW, after Cain and Able were born)
As for Adam ~not~ being the first person, the Bible gives tells us a number of reasons that make such a thought pretty hard to believe (or prove). For instance:
.........Romans 5
.........12
..Through
one man sin entered into the world,
and death through sin....
.........17
..By the transgression of the one, death reigned through the one....
.........18
..Through one transgression there resulted condemnation to all men....
I point to the part in bold above in particular, because if there actually were human beings living here for millions of years prior to the time of Adam, then the earth must have been become an awfully crowded place by the time he finally came along
~Deut
p.s. - the angels at the head and feet of Jesus in His tomb (as if He is the living Ark) is an interesting thought however (which is actually true of Him .. even though our Roman Catholic friends would have us believe that His mother, Mary, is the Ark instead).
.........1 Corinthians 15
.........45 ..So also it is written, “The first MAN, Adam, BECAME A LIVING SOUL.” The last Adam became a life-giving spirit.
