In the beginning, there was Adam. Becuase Adam was lonely, God made Eve. Adam and Eve had two children. Cain and Abel. Cain slew Abel. Cain then went out to find himself a wife. However, there are only two other humans in the world. Assuming he did not marry an animal, and he did not marry his mother, from where did this wife come from? It seems that Cain could only have married his mother or some future sister, unless God created more people than Adam and Eve.
Heh. Do the math: Each of us has 2 parents, 4 grandparents, 8 great-grandparents, 16 great-great-grandparents, etc. Keep going back and eventually you'd have more people than there were in the world at that time. None of them related? All are your great-great-whatever-grandparents? Nothing to do with religion, but it's impossible that there wasn't some funny business going on back there somewhere.
Read the story. The Garden of Eden with Adam & Eve was just down the road from Assyria, Persia, Arabia, and Ethiopia. Genesis 2:10-14 = https://www.biblegateway.com/passage/?search=Genesis 2:10-14&version=WEB;NLT;CEV;CEB;NKJV http://www.kjvbible.org/rivers_of_the_garden_of_eden.html The Adam & Eve story serves as the fountain for all of the other main characters leading up to Jesus. It has nothing to do with the rest of humanity.
And Cain was supposed to have been a vagabond and a fugitive. So much for that godly curse. Genesis 4:12 = https://www.biblegateway.com/passage/?search=genesis 4:12&version=WEB;NLT;CEV;CEB;NKJV

I caught this about Abel when I was a kid. I was being taught that I came, we all came from adam and eve. But clearly that is not true. And so, the story of god creating man and woman in eden is just a non factual story, that must have a deeper meaning, and is not to be taken literally. Which means you cannot take much of the bible literally. Hidden in those stories are deeper meanings, much like how a poem takes one to something deeper. So fundamentalists really don't have a leg to stand on in their beliefs. They are utterly wrong, and do not understand the deeper meaning which is probably spiritual in nature.
Genesis 5:4 - And the days of Adam after he had begotten Seth were eight hundred years: and he begat sons and daughters:
Where did these other people come from? There is no mention of them. Adam is the first. Eve is the second. Then Cain and Abel. Only four people living in the world. Where did these other people come from if not from the same family? That doesn't make sense. Adam and Eve were not just the first Hebrews, they were supposed to be thee first people. There are no other people, there was no humanity before them. So...he married his sisters?
Of course, either his sisters or his nieces. It is not impossible. Why was that so difficult to figure out for yourself?
Then why did you only list Cain and Able in the OP, as if to imply they were the only offspring of Adam and Eve?
No, the story is an allegory not history, but in Genesis it says "Then the LORD put a mark on Cain so that no one who found him would kill him. ... "4:15
The obvious answer from christians and maybe the other abrahamic religions as well. A&E had more than just cain and abel. The bible only mentions those 2 as the other's aren't important. But an answer outside of the religious dogma. There were multitudes of people already living outside this garden area. He went and found another human from another family. Since she wasn't part of A&E, the bible, torah, etc don't include them in the religious side of the story. - - - Updated - - - What? That's a new twist I hadn't heard before. At least not from an abrahamic god believer.
