Cain's wife is NOT the topic of this thread; rather, the wives of Enoch, Irad, Mehujael, and Lamech.
From whence did those men find their women?
Thank You.

If you believe that silence in the Bible is proof of something not having taken place, you obviously feel free adding your own unreasonable hypothesis, like adding a pre-Adamic race to the mix, or an alien race descended, or in whichever unreasonable direction you care to go.
The fact that specific women are not given a prominent role in genealogies, as evidenced by the genealogy in Genesis, and the geneaologies of Mary and Joseph (except for Eve, Rahab, Ruth, Tamar, Uriah'wife, Mary), and that women generally are not mentioned in geneaoligies, only means there are women we don't know much or anything about, i.e., Cain's wife and the wives of Enoch, Irac, etc. The fact God's word says HE created Adam and then Eve from Adam, and says nothing of creating another man or pre-Adamic race of men separate and apart from Adam and Eve, indicates that all the wives of all the men in Genesis came from one bloodline, namely: the bloodline of Adam and Eve.
One other thing to keep in mind is that the blood-line created by God in Adam and Eve was not yet the corrupted line it is today, but rather it was the closest to pure that it ever was. People were living longer than 900 years and producing babies. The weathering process (the solar effects on humans) and the atmospheric conditions generally were not like we know today.
Therefore, it is only reasonable to conclude that Adam and Eve had lots of baby girls that grew into women/wives for their brothers and their nephews, and their cousins, etc. And when those brothers, nephews, cousins, etc, took their blood relatives as wives, they too produced baby girls who would grow up to become women/wives for men in their own bloodlines.
It's error to infer a pre-Adamic race when scripture clearly says that God created two to be fruitful and multiply, Adam and Eve.
