That’s entirely possible. I tend to agree with it. I refuse to believe God created anything that was void and formless. No way. Isaiah 45:18 I believe the earth became formless and void, but was not created that way.
Where did Adam’s sons get their wives.
They married sisters. The human race was not as polluted, as is now. Technically, since we all descended from Adam and Eve, (and Noah) we are all related. When we marry, we are marrying a relative, just not a close relative.
Between Genesis chapter 1, verses 1, 2..and the rest of Gen.. The earth was without form, and void, and darkness upon the face of the deep. Suggesting something had happened or it existed in that condition.
God spoke the creation ...light, seas, animals, Adam.
