Evolutionists will show charts of a mini-horse supposedly evolving into a larger horse over "millions" of years, but the problem is that they are all "horse kind." I can do the same thing right now--take a picture of a Chihuahua and put it on one end and a Great Dane on the other end, and fill the middle in with smaller to medium-sized to large dogs and call that "evolution" but they are all still dogs and all just different sizes. It proves nothing. The dogs didn't change to a horse--they are all still dogs. Natural selection isn't evolution. Animals changing from one type of animal into another would be considered evolution, and that has never been observed or demonstrated, and therefore cannot be classified as "scientific proof." It is something that has to be taken by faith.
