Such an amount of time would mean a complete reset of everything. Each civilization would have to basically start fresh.And 8 great civilizations seems reasonable. If you consider ours for the last few thousand years one civilization, gaps of tens of millions of years between civilizations with nothing much happening seems perfectly reasonable to me.
In any case, it's not a deal breaker for me. Even with a full reset between each civilization, that's 111 million years between each. Plenty of time to have us do all these things and lose them again to start over.
