Opponents of the intelligent design theory accuse it of failing to have any facts to support its claim since it is mainly based on beliefs. Additionally intelligent design has been heavily criticized by theUnited Statesnational academy for sciences.
The academy has criticized the theory due to the fact that their arguments cannot be tested by experiment, they do not propose any hypothesis and in addition they do not generate any predictions. On the other side critics of the evolutionary theory accuse the proponents of the theory to lay claim on facts that have been observed yet they cannot prove how life came into being.
The evolution theory is closely related to social Darwinism.
