I believe there are hybrids on the earth as a result of what happened in Genesis 6:1-4, but I'm not sure that I believe that Eve had sex with Satan and produced Cain. However, I could be wrong and not seeing it, but it hasn't rang true to my spirit, nor do I find scriptural truth to it anywhere.

How to explain this verse of Adam having knowingly taken the fruit from Eve and eaten of it if we are talking about Eve having sex with Satan? "And the man said, The woman whom thou gavest to be with me, she gave me of the tree, and I did eat." I mean, weren't Adam and Eve already having sexual relations before this serpent event??? "And they were both naked, the man and his wife, and were not ashamed." <Genesis 2:25>. They were man and wife BEFORE the serpent/Eve/fruit event happened.

Also look up the instances of the word "fruit" in Genesis in a Strong's. In the instance of Eve eating of the fruit of the tree of the knowledge of good and evil, it has this Hebrew word: "p&#277;riy" <Genesis 3:6>

Then, if you read the account of Cain bringing the fruit to the Lord as an offering, it is also that same Hebrew word for fruit: "p&#277;riy" <Genesis 4:3>

So if we are to believe the Serpent Seed theory that the meaning of "fruit" in Eve's account means "sexual relations," then how does that correlate with the story of Cain bringing his fruit of the ground to the Lord?
