School question

[Ashendant]

The earliest creation science texts and curricula focused upon concepts derived from a literal interpretation of the Bible and were overtly religious in nature, most notably linking Noah's flood in the Biblical Genesis account to the geological and fossil record in a system termed "flood geology". These works attracted little notice beyond the schools and congregations of conservative fundamental and evangelical Christians until the 1970s when its followers challenged the teaching of evolution in the public schools and other venues in the United States, bringing it to the attention of the public-at-large and the scientific community. Many school boards and lawmakers were persuaded to include the teaching of creation science alongside Darwinian evolution in the science curriculum.[7] Creation science texts and curricula used in churches and Christian schools were revised to eliminate their Biblical and theological references, and less explicitly sectarian versions of creation science education were introduced in public schools in Louisiana, Arkansas, and other regions in the United States.[7][8]

"The 1970's" is kind of vague, but it doesn't sound like he's far off the mark.

In 1987, the United States Supreme Court ruled that creationism is religion, not science, and cannot be advocated in public school classrooms.[80]
