Are there any other scientific theories for creationism other than the big bang and evolution?
There are some heterodoxical theories but in main the scientific evidence leads to the big bang and evolution. By the way, the big bang cosmology and the biological theory of evolution are unrelated to each other. Either theory could be true without the other one being true. Another cosmology theory was the steady state theory. All scientific biological theories accept some type of evolution; however, the speed and reasons for evolutionary change depending upon the theory of evolution. Lamarck had a completely different theory of evolution than did Darwin. Darwin’s theory of evolution via natural selection, however, is the accepted theory today. But it has been updated with genetic evidence, etc.
