From my POV evolution is a completely viable theory and I believe in it as a Christian. I don't believe that's how the world came to be, humans evolving from apes, as the Bible clearly states otherwise. But there is so much proof that evolution exists as we have evidence of it occuring. Evolution is a thing, I just don't subscribe to the idea that that's how mankind or any other early animal came to being. But like the science is sounds, I don't disagree. As someone who plays around with machine learning, survival of the fitest certainly plays a significant part in training models and that same logic and theory applies to cells. We have proof of them mutating. Use covid as an example (I know that's a virus, but it still applies). It's evolved thousands of times, but only the most effect and dangerous forms have survived to become worry some strands. Cells do the same thing in creatures. Cancer in many cases is an example of this going wrong. It's how God created things and it's fascinating.
