I've heard that:
1. Emet-Selch has lived a thousand thousand lives (since sundering?), or so he says.
2. It was about 12-13,000 years ago that the sundering happened.

It seems like there (2) is the one we have the most evidence for / statements from producer. But isn't that inconsistent with (1)? That is, unless he lived most of that time before the sundering. But that's a long time; feels unlikely to me. Maybe he's just exaggerating?
