Science was created in an effort of people to survive in given circumstances and to explain their existence to themselves, mainly by proving that God is the creator of all life . Today we know that all living things have a common denominator, DNA. Without DNA there is no life. All life forms, i.e. substantive content of life, can be broken down into individual components and their functions, which will ultimately always lead us to DNA molecules. Therefore, we undoubtedly know that all life is based on a code written in DNA molecules.
