Evolution and ID are competing theories for how living creatures change over time.
Evolution believes it is random chance that determines the next step.
ID believes it is a deliberate mechanism that chooses the next step.
Time and more study will reveal which is the superior theory.
Why do evolutionists act like ID is a threat if it is just creationism in disguise?
In its modern iteration ID was created after the U.S. Supreme Court removed creation "science" from the classrooms.
ID is designed to fool people and to push a particular view of religion while pretending to be science. As such, it is a lie from start to finish.
