Undeniable evidence? Name one fact about evolution. You will find that it's anti-science. Everything that we observe on this earth devolves. The law of entropy alone proves that evolution is an inverted fantasy.
By bringing up entropy, I will assume that you are simply referring to the second law of thermodynamics.
The usual anti-evolution argument that abuses the second law usually says something like "Everything tends toward increasing entropy (randomness and disorder). Evolution of life involves the development of great complexity and order. Therefore, evolution is impossible by the second law of thermodynamics." While it sounds simple, there are major flaws in this argument that render it worthless.
It is only in isolated systems that entropy must increase. Systems that can exchange energy with their surroundings have no such restriction. For example, water can freeze into ice (becoming more ordered and decreasing its entropy) by giving up heat to its surroundings (this increases the entropy of the surroundings, of course). In the case of the Earth, the Sun is a major source of energy, and the Earth also radiates energy into space. One consequence of thermodynamics is that, when energy comes from a "hot" source (like the Sun) and is output to a "cold" reservoir (like space), it can be used to do work, which means that "complexity" or "order" can be produced. The main point is that, for a non-isolated system, an increase in "complexity" (to the extent one can connect that concept with the thermodynamic entropy, which is far from straightforward for living creatures) does not necessarily indicate a violation of the 2nd law. A good example is the development of a human fetus into an adult; this is the production of a more thermodynamically complex system but involves no violation of the laws of thermodynamics.
That is from an expert of molecular thermodynamic's
website , because he could put it into much easier words than I can (he also knows a whole lot more than I) He also happens to be a devout christian.
To touch more on Evolution as a theory. A common argument by proponents on creationism and intelligent design is that Evolution is JUST a theory - and this is true. If you are skeptical by nature, unfamiliar with the terminology of science, and unaware of the overwhelming evidence, you might even be tempted to say that it's "just" a theory. In the same sense, relativity as described by Albert Einstein is "just" a theory. The notion that Earth orbits around the sun rather than vice versa, offered by Copernicus in 1543, is a theory. Continental drift is a theory. The existence, structure, and dynamics of atoms? Atomic theory. Even electricity is a theoretical construct, involving electrons, which are tiny units of charged mass that no one has ever seen. Each of these theories is an explanation that has been confirmed to such a degree, by observation and experiment, that knowledgeable experts accept it as fact. That's what scientists mean when they talk about a theory: not a dreamy and unreliable speculation, but an explanatory statement that fits the evidence.
