BTW, several evolutionists on this forum (myself included) are Bible-believing Christians. However, we see Genesis as an allegory rather than being literal.
I can think of a few. Because -- according to creationism -- all species were specially created at virtually the same time, and did not gradually evolve from earlier forms:
1. There should be no transitional species.I shall call these The Five Failed Predictions of Creationism.
2. There are most certainly no pre-human species.
3. There should be no evidence, whether in fossils or DNA, showing the chronological evolution of life.
4. There must surely be at least one species, and probably several, having no genetic similarities with any other life on earth.
5. The fossil record must show all kinds of species living together at the same time.
4. There must surely be at least one species, and probably several, having no genetic similarities with any other life on earth.can't yet be accounted as totally failed predictions. In fairness, all we can do is point out that the predicted evidence has not yet been discovered. (And given the lack of actual research being conducted by creationists, it is unlilely to be discovered.)
5. The fossil record must show all kinds of species living together at the same time.
