Why?
OMG, scientific guesswork...Must..believe...unwaveringly.
Some wonder how any life could have survived such a deep freeze.
How is this even plausible at all? Partial glaciation is one thing. But aside from the planetary orbit being moved another half-million kilometers away from the Sun (possibly dragged out of orbit by a passing super-dense celestial mass like a stellar core fragment, for example), what else would even cause a complete north-to-south global freezing? And if it occurred then how could it even naturally reverse itself without a massive increase in stellar activity from good ol' Sol?
I have major doubts on this one. This is veering dangerously close to Erich Von Daniken's tin-hatter territory.
