Blandiver, just like many evolutionist ideas are now jettisoned some creationist models are also out of favour now. The vapour canopy being one such , as it is now thought that it has little explanatory power , though possibly contributory.    I won't laugh, but I hear that many schools teach that mankind arose from microbes over eons , and that life somehow arose from non life despite there being no evidence of this or of how it could be possible.   Thankfully there are some, albeit very few, that resist this indoctrination.
