So you are saying that HUMANS lived with the DINOSAURS? Brother in Christ, as a Christian, I do indeed believe that god created all of life and the universe, but come on. Over time, an animals’ environment will change. As that animal begins to lack something it needs to survive, it will eventually breed newer, more resilient genes into its offspring. This offspring will eventually have its offspring, which will have different traits from the other parent. Over thousands of years, the genes will have changed so much that the beginning and end genomes will be different from each other, resulting in a new species. This is how dinosaurs turned into birds, prehistoric mammals into modern ones (like humans) and bacteria into everything on earth, from plants to animals to fungi. See, god is making evolution. He is simply controlling a creatures’ destiny by making tweaks and changes to its traits so it and its offspring can carry on their line for as long as possible.
