I just realized something and it makes no sense

So in S6E1 Earth in dimension C-131 got Mr. Frundeled meaning that everyone on it is technically dead and even if Mr Frundlesgot killed Earth is already destroyed. But in S5E2 we see time skip with wooden Jerry where in future there are dolphin people, bird people and shit like that but how the hell is that possible when Earth from that universe was destroyed before any of that could happen?
