It isn’t certainly old, but creationism is still used in US schools, with not better content. I remember a US delegation not so many years ago, wanting creationism as an alternative teaching in European schools and their anger when they were sent to comb the desert. Even in religious schools the religion is separated from academic teaching. This is not the case in the US, where creationism and also scientology are taught as themes equivalent to real science, even in universities.
