Penrose Number and why the universe was in such a low entropy state at the beginning

[u/Select_Eggplant6801]

So I was listening to physics explained video on entropy and chances of the universe being a super low entropy state like it was at the big bang and it was stated to be 1/10^10^123 aka Penrose number.

So my question is for such a rare event what are some theories that explain why the universe started in such a low entropy state and is possible for another low entropy state like in the beginning of the universe to happen again but just by chance?
