Current evolution theory, at best, is somewhat reminiscent of newtonian mechanics trying to account for all the forces in the universe.
The main problem with it is that people started with what they wanted to believe (that God doesn’t exist) and then they sought evidence to back up that desired belief. They didn’t start with an unbiased search for the true nature of things. People don’t want God to exist because they want truth and morality defined as they see it best. It’s like a drug addict not wanting to accept he has a problem because then he’d have to give up his drugs (even though doing so would inevitably make him happier and make his life more fulfilling).
Newtonian mechanics fit an easily observable description of the natural world several hundred years ago, but the principles were never fundamental. They only described certain pieces of nature with certain numerous constraints. While it seemed like a broad science from our point of view, it’s scope was extremely narrow when the microscopic and macroscopic portions of the universe were taken into account (and these portions are really the most substantial). When Einstein wrote his special theory of relativity and the direct correlation of matter and energy, the world view of physics was forever changed because time and space (or distance more specifically) were no longer constant and concrete concepts. Is essense, Newtonian mechanics was wrong and it only gave accurate predicictions within a narrow band of parameters. For those more familiar with physics, a good analogy would be the small angle approximation for a pendulum. Although for small angles, this simple approximation yields relatively accurate answers, they are not correct answers. One must resort to the ever painful elliptic integrals to truly get correct answers.
Taking the ‘evolution of physics’ a step further, even the special theory of relativity failed to provide a complete description. So thus came Einstein’s general theory of relativity and also the birth of quantum mechanics. General relativity worked wonders and described spacial curvature and distortions caused by matter in gravitational fields (things on very large scales), while quantum mechanics gave extremely accurate predictions about those things on the subatomic level. Quantum mechanics was truly bizarre to the physics community at first because it was even less intuitive than relativity. The famous double slit experiment for light also held fast for electrons which showed that matter itself was a wave. In parallel, Heisenberg’s uncertainty principle showing it was actually impossible to measure with perfect precision both the position and velocity of a particle which gave way to the probabilistic weirdness in the quantum world. Such concepts as walking through a solid stone wall (quantum tunnelling) are actual possible (although with very small probability) within the theory of quantum mechanics. But even with all these drastic new changes of perception of the physical world, the theory was still wrong.
Quantum mechanics and general relativity could not be rectified when dealing with things both very small and very massive such as is the case with spatial singularities (ex. black holes) or in conditions of the early universe. Theoretical physicists concluded that at distances around the planck length (~10^-33 cm), the smooth curvature of space (and even time) broke down completely and that space and time became turbulent and chaotic. Certain probability equations broke down yielding infinite answers. A probability greater than 1 is weird in itself, but infinity? So what now?
Well the entire particle concept of subatomic physics would never be sufficient to explain the deeper mysteries of the universe, and in essence, was wrong. Hence came the string theorists. Without getting too in-depth, string theory actually asserts that space-time may be discrete and that it makes no sense to even discuss distances shorter than the planck length. If it’s true that the universe is really composed of little 1 dimensional loops vibrating at different frequencies (i.e. a loop vibrating at one frequency would be an electron while at a different frequency the same loop would be a photon), then this theory will have solved the conflict between quantum mechanics and general relativity. But again the entire world view of things will have changed. And after it’s all said and done, how much deeper will we be able to go and what flaws might we find with this theory down the line?
To conclude, the nature of the universe is so far off from Newtonian mechanics that it can’t even be considered as good as a small angle approximation on the grand scale of things. Then there’s the theory of evolution - and analagously, Newtonian mechanics actually looks like a crown jewel compared to the flaws and holes in evolution theory. Evolution theory was not created to prove anything, but rather to disprove God. It’s Daffy Duck on the side of a rock face that keeps springing leaks. First his hands plug the leaks, then his feet, then his beak, until eventually he swells up internally and is blown completely off the rock face.
As a final note, I’ll say that if string theory is accurate and the universe really is a symphony of vibrating strings, then wouldn’t that be the ultimate voice of God? Let there be light.
