There are many “pop-science” articles showing up in the media, suggesting that life on planet Earth is not unique. They are suggesting that there may be other chemistries with different molecular structures elsewhere in the cosmos. The truth is that the chemistry of water is essential to life.
The key to this question is a basic chemistry issue involving the water molecule. We have posted previously on the nature of the water molecule. You can also access articles from our printed publications by using the search engine on doesgodexist.org.
The main point is that the water molecule is polar. The bonding positions on the oxygen atoms in water are 105 degrees apart. Because of that, the two hydrogen atoms that bond with the oxygen atom are on one end of the molecule and oxygen is on the other end. That makes the water molecule polar, and it gives water unique properties, including the ability to dissolve most inorganic compounds.
Discover magazine (July/August 2019, page 82) carried an excellent explanation of why the chemistry of water is essential to life, making it possible for life to exist. Here is a quote from the article:
“For the chemical processes of life to happen, molecules must be able to connect, separate, and reconnect in specific ways. Think about DNA replication, for instance. The base pairs that make up the genetic code bond when their negatively charged hydrogen atoms are attracted to positively charged atoms in another nucleotide. Those bonds hold the two strands of the double helix together, but because hydrogen in water molecules also bond this way, it’s relatively easy for enzymes to ‘unzip’ the double helix for replication, then bind the two new strands together again. However, the molecules of life won’t work in hydrocarbons the way they do in water. That’s because most hydrocarbons don’t tend to form hydrogen bonds.”
In Genesis 1:2, the very first action of God on the newly created Earth is that His “Spirit moved on the face of the waters.” In Proverbs 8, wisdom speaks of the fact that in the creation process there was a time when there was no liquid water (Verse 24). We are finding water scattered throughout the cosmos, and it has become pretty apparent that water was a created and carefully designed tool to allow the basics of life. The chemistry of water is essential to life.
In baptism, we see water having a spiritual significance as well. Water is essential to much of God’s plan and compelling evidence of His wisdom and design in all areas of our existence.
