[Marvel] Is there a greater point/impetus for the Multiversal cycle of rebirth and death?
So I know it originally began with the Celestials warring against the First Firmament and broken pieces becoming the 2nd Cosmos, but is there a reason why the cycle has repeated so often that there are 7 previous Multiverses? Is there some kind of greater point or reason for the Multiverse to be recreated and destroyed like this?
Or something moving it forward? Why is it still going on?
And a reason why the last survivor becomes a Galactus figure in the next multiverse?
What is the The One Above All doing with this?
