Life from Non-life by Chance

Life from Non-life by Chance - DNA Molecule

Let’s consider the possibility of life from non-life by chance. The simplest living organism is an anaerobic bacterium known as Pelagibacter ubique, which was first isolated by scientists in 2002. Anaerobic means that it does not need oxygen to survive.

Anaerobic bacteria are much simpler than aerobic bacteria, which do require oxygen. This bacterium lives in the lakes and oceans of the world. In 2005, scientists sequenced (decoded) the genome (genetic material, DNA) of P. ubique. They found it to be the smallest genome with the theoretical minimum of information needed to exist as an independent life.

P. ubique has 1,308,759 base pairs, which are pairs of the essential biological compounds that are held together by hydrogen bonds to form the DNA molecule which contains the “blueprint” for each living organism. Each of the components of the base pairs, called nucleobases, are complex biological compounds containing nitrogen and other elements.

There are four nucleobases in DNA, and they are adenine, guanine, cytosine, and thymine. They are typically abbreviated A, G, C, and T. The DNA molecule is present in every cell of every living organism, and the arrangement of those nucleobases describes the basic features of the organism.

We have vastly oversimplified this explanation, but I think you can see our point. Let’s go back to those 1.3 million base pairs in the simplest living organism. What do you think is the possibility of all the essential elements coming together to form the compounds and molecular structures to create the simplest form of life from non-life by chance with no guiding Intelligence? We have one word for it. IMPOSSIBLE!
