The evolution theory states that a primitive life form appeared by chance and that by successive genetic mutations, speciation and evolution, complex and superior forms of life gradually came in existence. A simple combinatorial model was used to assess the probability that the genes that form chromosomes come in the right sequence by chance, in the primitive form of life. A possible conclusion, based on this simplified model, is that the hypothesis that the primitive form of life came in existence by chance is considerably less probable than the hypothesis that life, even the most primitive form, was created.
