@rosborne979,
Snowball earth is a belief system. It doesn't take into account plate tectonic drift which could have caused continents to be at the poles periodically, nor does it offer an explanation of how it ceased.
The more ice there is on the surface the less energy is absorbed from the sun because the whiteness reflects it back to space. Thus, once established it ought to become permanent. Which it isn't. As you all know.
The belief system has its popes, its cardinals, its bishops, its clergy, its lay dupes and assorted hangers on hoping to make money out of human stupidity, theological texts, catechisms and various dogmatic mantras designed to be easily remembered. It has nothing to say about courtship rituals, marriage customs, sexual practices, art, double entry book-keeping, Faustian mathematics, law and order, periodic festivities, manners, etiquette or anything else of significance to normal people. It's a form of intellectual suicide: the avoidance of a proper brain-life. It takes us nowhere and if anybody thinks it is going to touch, never mind undermine, the objectors to the teaching of evolution they are living in cloud cuckoo territory.
