There can be no life without information exchange in the living cells. That is the difference between non-living cells and living cells - for life to continue and for cells to duplicate or replicate themselves, there must be information within the cells, which the cells use by selecting the appropriate bits of info to trigger just the right chemical reaction that will enable the cell to do what it must to do keep living, or to replicate itself.
Just ask yourself - does information require an intelligent source, or is information randomly and chaotically scattered all over the universe so that life will proliferate without any intention or design?
When Watson and Crick discovered the structure of DNA in 1953, it was realized that the specification for life is 'written' on huge molecules using an elegant genetic language having an alphabet of just 4 'letters'. Yet that is not proof of the existence of an Intelligent Designer of DNA. Here's the proof...
Information is stored on DNA molecules, transcribed on to RNA molecules and translated into proteins (the work-horses of the living cell). The processes of storage, transcription and translation closely mimic an advanced human language, involving codes, syntax and semantics.
This 'language of God' (as Francis Collins, leader of the Human Genome Project, calls it) is present in all living systems and, without it, no life would be possible. It follows that the essence of life resides not in chemistry but in information and communication - things that can only be the product of intelligence - not chance - and which the hypothesis of God would lead us to expect.
Get the book below, all you who want to learn the vast complexity of individual living cells selecting (choosing) and pairing up just the right chemicals for just one particular task.
