You Are Left-Handed
If I were to ask you whether you are left-handed or right-handed, you would probably answer with most people that you are right-handed. While that may be true, you are also left-handed … and your life depends on it.
Biologists have absolutely no idea why molecules of living things are left-handed. You see, when biological molecules are made in "origin of life" experiments, they are always a mixture of both left-handed and right-handed molecules – mirror images of each other that won't work together in living things. A right-handed amino acid can be chemically identical to a left-handed amino acid. But for some mysterious reason, a living organism will treat the right-handed amino acid as if it were useless, even though normal chemical reactions ignore the difference. This tells us that living things are much more that just the result of chemical reactions. As the Bible suggests when it describes the creation of life, living material is different in some very important ways from nonliving material.
The fact that life uses only left-handed versions of biological molecules poses another problem for those who think that life formed spontaneously without a Creator. While experiments show that some simple biological molecules can be formed in the laboratory, experiments always produce a mixture of left- and right-handed molecules.
So life's origin, with its left-handed-only molecules, remains a mystery to those who reject the Creator. Could this be why God designed life with left-handed only molecules in the first place?
