Have you ever wondered how Charles Darwin and his theory of evolution advanced scientific knowledge and freed mankind from superstitious beliefs? Well, now I find myself in a dilemma just like some of you. Since we were children we have heard from our parents that God created the earth, and all the living beings that inhabit it today. In addition, the biblical account of creation is reliable and that evolution is nothing more than a theory, a theory that does not have the support of evidence. Next we want to share a subject that is still not clear for some of us, please join me to give your opinion on this matter.
At some point in life, we all have to ask ourselves the question: is life the work of a creator, or the product of evolution? Most probably you still have doubts like me, so we have tried to summarize the subject well because there are many concerns and I do not want to bore you, what I want is to share the information. Let everyone draw their own conclusions.
How did Life begin?
When we were children, we surprised our parents asking them where babies come from, in that case depending on the age we were and their personality, maybe they turned a blind eye or gave a hasty and evasive answer, or told a fantastic story that later we discovered that it was not true. Obviously for a child to be well prepared for adulthood and marriage, he or she must eventually learn about the wonders of sexual reproduction. Just as there are parents who find it violent to talk about the origin of babies, there are also scientists who are reluctant to talk about an even more transcendental question: Where did life come from? A plausible answer can have a profound impact on our philosophy of life. So how did it all begin?.
What do scientists say?
Many will tell us that life began billions of years ago at the edge of a tide pool or at the bottom of the ocean. They assume that in such an environment, some chemical compounds randomly assembled to create bubble-like structures, formed complex molecules and began to reproduce. According to their thesis, every form of life on earth originated by chance from one or more of these simple primordial cells.
Other eminent evolutionary scientists are not of the same opinion. They conjecture that the first cells, or at least their main components, arrived on earth from space. Why? Because the best efforts to demonstrate that life can arise from inert molecules have been unsuccessful. Underlining this difficulty, biology professor Alexandre Meinesz said in 2008 that over the past fifty years "no empirical evidence has supported the hypothesis of the spontaneous appearance of life on earth from a simple molecular soup, and no significant advance in scientific knowledge points in this direction," he said.
What does the evidence reveal?
The answer to the question "Where do babies come from? It is very well documented and not controversial. Life always comes from pre-existing life. Now, is it possible that in the remote past this fundamental law was violated? Could life have arisen spontaneously from inert matter? How likely is it that such a thing could have happened? For a cell to survive, experts say, it requires the joint intervention of at least three types of complex molecules: DNA (deoxyribonucleic acid), RNA (ribonucleic acid) and proteins. Few scientists today would argue that a complete living cell was formed suddenly by chance from a mixture of inanimate compounds. But how likely is it that RNA or proteins would do so?.
Some authors, says Robert Shapiro, professor emeritus of chemistry at New York University, have imagined that all the components of life were already found in meteorites and could be easily formed by experiments similar to Miller's. Let us examine the RNA molecule, itself made up of molecules called nucleotides. A nucleotide is different from an amino acid and slightly more complex, the presence of a nucleotide has never been detected in the products of electrical discharge experiments, nor in meteorite studies, says Shapiro. He adds that the probability of a self-replicating RNA molecule assembling by chance in a pool of chemical building blocks is so small that its occurrence, even once, anywhere in the visible universe would be considered something of a miracle.
The human body is one of the most sophisticated structures in the universe. It is composed of approximately one hundred trillion (1014) tiny cells: bone cells, blood cells, brain cells... just to mention a few. In fact there are more than two hundred different types of cells in our body. However, Darwin thought that all living organisms shared a common ancestor and imagined the history of life on earth as a big tree. But scientists imply that the fossil record proves the theory of the common origin of life. And since all living things use the same type of computer language or DNA, they claim that all forms of life must have evolved from a common ancestor.
What do you think, what conclusion do you reach regarding the origin of life, in view of the controversy generated around these pillars of Darwin's theory, can it be honestly stated that his version of evolution is a scientific fact?.
