This is a very challenging question. my answer which is a matter of opinion is both. I believe God made everything at the beginning of time. I also believe that living things do evolve to survive in changing environments. And man has evolved to adapt to his environment. For example people living in malaria areas have gene modifications that make them resistant to malaria. These mutations are not found in Europeans or Canadians for example. That means we have evolved to cope with disease. Other living things like bacterial mutate to develop resistance to antibiotics. Malaria parasites evolve to become drug resistance. Even mosquitoes have evolved to become resistant to insecticides. I guess it is ok to be a christian and a scientist. And believing in evolution does not mean that you do not believe in God.
