Man in his sinful ignorance interferes with what he cannot understand. The process of life in forming a person has been established by God. Mans trial and error science is primitive and foolish which will only lead to further iniquitous results. This is similar to the tower of Babel a misguided incident if ever there was.
Genesis 11:9 Therefore is the name of it called Babel; because the LORD did there confound the language of all the earth: and from thence did the LORD scatter them abroad upon the face of all the earth.
