I did some checking. State creationism laws were passed during the 1980's in Arkansas and Louisiana, to force the teaching of creationism in place of evolution. In a 1987 case, Edwards v. Aquillard, the U.S. Supreme Court ruled that these laws were unconstitutional because they violated the establishment clause of the 1st Amendment of the U.S. constitution. Creation science was seen to be a expression of religious belief. It was judged to be not a true science because it could never be falsified as it was firmly held as a religious belief by its adherents that no amount of contradictory physical evidence could change.
It is not like my pal to say something without knowing the facts. I however checked out with him just to satisfy my own mind and he did NOT say it was STILL illegal. He said it used to be forbidden in certain states. I picked him up wrong. So I stand corrected. He did however say that in HIS school creationism even to this day was taught alongside a toned down version of evolution based on creationism which did not resemble the true scientific facts. SO it might as well be illegal or not have been taught at all for all the good it does.
