The Problem of Incest
In Genesis the creation of Adam and Eve the first two humans is described, it says Eve is "the mother of all the living" Gen 3:20 (NIV) (i.e. All humans are descended from Eve). Now we come to the first problem in Gen 4:17 it describes Cain (Adam and Eves son) having intercourse with his wife, the only explanation for the sudden appearance of Cain's wife is that she is one of his sisters (or Eve). Even if this passage were not in the Bible the only possible way to populate the Earth with just two people is if someone has incest and intercourse with another member of the family (because there is only one family). Now if we skip a few chapters to Leviticus 18:6-21 God clearly forbids the act of incest "No one is to approach any close relative to have sexual relations. Lev 20:11-12 describes one of the punishments for committing incest as death and also describes it as "a perversion". Lev 20:17 forbids incest between brother and sister saying -"it is a disgrace."
This could be explained by saying that incest was allowed because all humans were 'pure'. This however is not true, if you look at it from a biological view point even if both the mother and farther are 'pure' it doesn't mean their offspring will be 'pure' because there is always a small chance of genetic mutation occurring. If you look at being 'pure' from a spiritual view point then again it is not true, in fact the first humans in the bible were committing sins and were just as impure then as humans are today. For example Adam and Eve commit the first sin by eating the apple in Gen 3:6, Cain murders his Brother in Gen 4:8 and as described above there must have been a lot of incest happening. So the argument that incest would have been allowed because humans were pure does not stand up.
Another possible explanation that again does not stand up is that Incest was allowed because God had not yet forbidden it. Even if God had not told humans that incest was wrong and sinful, God must still have held the view that it was wrong, yet God did not punish anyone, but we see an example of God punishing some one for sinning even before God has communicated that it is a sin in Gen 4:11 were Cain is punished for the murder of his brother. In Gen 4:8 Cain breaks the 5th commandment ("You shall not murder") (Ex 20:13) but God has not yet given this commandment but still punishes Cain. So it seems that God is inconsistent when it comes to punishing people.
There is a simple and logical way God could have populated the Earth while completely avoiding the problem of incest. If several humans had been created from the ground instead of just two then there would have been no need for incest to occur as there would be no need to have intercourse with a family member, now you would think that this solution would have occurred to an all-knowing God wouldn't you.
