I don't take the hypothesis of the Precambrian 'snowball' particularly seriously, but I'm aware of it. It may have happened, and it could happen again; but the event itself predates everything alive today.
     To date, the only time I've seen this thing come up as 'evidence' of a global flood was when I've handed it to the creationists to see whether their pathology allows them to sieze something they know nothing about [and which, for all they know, I'd just made up] and use it as 'proof' that the bible is accurate. Unfortunately for the creationists, the Precambrian 'flood' predates not only homosapiens and deinosaurs, but trees. There was nothing multicellular around to build an ark 700million years ago, and nothing to build it with.
     As for the hypothesis itself: the evidence supporting it is a bit weak: 'a glacial deposit with undeniable tropical origins. The deposits' telltale sign- the "magnetic signature" found only in rocks forged near the equator- is the central bit of evidence that the Earth was once entirely locked in ice'. I tend to question 'undeniable tropical origins' until I see a reason for them to be undeniable. It wasn't long ago that the worldwide irridium layer [evidently residual from a meteroic strike at the end of the Maastrictian] came from 'undeniable volcanic origins', after all. and, of course, I'm a bit perplexed by the declaration that 'Literally, all Hell broke loose'; apparently, I have a different definition for literally here.
