Short Answer

Evolutionism violates many easily observed scientifically proven principles. Evolution isn't science. Two of the most obvious of these scientific laws that evolutionism violates are the First and Second Laws of Thermodynamics. There are countless additional examples.

Detailed Answer

It's interesting to note, that the most troublesome presuppositions tend to follow whatever is politically correct at the time. When it was politically correct to assume that the earth was the center of the universe, that particular presupposition left scientists with an improbable, unworkable hypothesis. The more they observed the movements of the planets, the more they had to make up strange, improbable stories about how the planets and stars moved. They were very inventive, intelligent and persuasive.

Today, evolutionism is the number one improbable, unworkable hypothesis that results from the prevailing presuppositions. There are some who say that nothing is impossible, but evolution comes as close as anything to showing that some things are impossible.

Just the violation of the second law of thermodynamics alone makes evolution a silly theory.
"...there are no known violations of the second law of thermodynamics. Ordinarily the second law is stated for isolated systems, but the second law applies equally well to open systems.
...there is somehow associated with the field of far-from-equilibrium phenomena the notion that the second law of thermodynamics fails for such systems. It is important to make sure that this error does not perpetuate itself."

Even though this is true, there are many deceptive persons who are willing to use all sorts of false examples and false data and false logic to try to cloud the issue. Sometimes, they don’t even bother addressing the problem but make a statement that indicates that the second law of thermodynamics is not an issue or that the creation scientists don’t understand the second law of thermodynamics. Of course this is all flimflam, showing that evolution is a religious belief of Humanism.

Scientific observations continually uncover more flaws in evolutionism. Scurrying to preserve the hypothesis, evolutionists stretch the limits of rational-lie-zed speculation with ever greater misrepresentations. One would tend to wonder how anyone who thinks in the loops of rational-lie-zed speculation could solve any problems in the real world.

Yet, many colleges teach that evolution is an undeniable fact. And some people think that evolution is valid. There is certainly much coercion that makes people, at least in public statements, say that they believe that they are descendants of fish. You don’t really believe that, do you?

Summary

Evolutionism is obviously false. Evolution isn't science. It violates what can be easily observed.
