One questions you have to ask if you want schools to teach creationism is, WHICH creation story? The Judeo-Christian one is going to be some people's answer, but then you have an official state religion, which is, as far as I know, still unconstitutional.

Another question is, who would you get to teach it? You can't discriminate based on religious beliefs, so you could have an atheist teaching kids about God It could be a Pagan or Witch or Buddhist or... you get the picture. When you take religious teaching out of the hands of the religious organizations, I fear it might end up with a whole new spin based on the lack of belief of those who teach it.

My bottom line here is, if you can explain it to someone from the planet Ggryufis who understands English and has been briefed how not to get arrested or beat up. If you can show what evidence you have and explain your best theory based on that evidence, and it makes sense to the alien, you've got science.

I don't think this would work with any religious beliefs. Especially not if our alien explorer knows for a FACT that his own personal gods created the universe, and Earth happened because Hork (May His Name Be Praised) forgot to clean out his cosmic refrigerator a couple of Ggryufisian weeks ago.
