Evolution and science
Evolution and science conflict with each other. Evolution is clearly atheistic and a pseudoscience, easily disproven by numerous counterexamples to evolution that exist. Evolution is not real science because it makes guesses as to what happened in the past, which cannot be observed and is not repeatable, while real, observational science can be observed through repeatable tests. While creation science is similar to this, the evidence, including in science, in history, and in divine revelation, points to something other than evolution and long ages.
Creationists also disagree with evolution as it requires a time frame of billion/millions of years. This is incompatible with their time frame for creation of approximately 6000 years, as derived from the Bible.
