So then life has always been the same from the time of creation until today? If that's the case, then why don't we find any fossils that appear to be modern cows, horses, people, etc.? If it's not true that life has been the same since the time of creation, then by definition life has evolved. Therefore the theory of evolution must be true (at least in its general principles, not necessarily in its details). First, I never said that. There is an enormous difference between between minor or even moderate adaptations within a species and one species changing to another.
