As you said that reincarnation is a very confusing topic and you will not find a clear description of it anywhere because even a clear description seems like a story to people. It cannot be believed so easily. It is the destiny of every person to understand the way of this universe.

Just like there is a good time and a bad time, similarly when the right time comes to a person at his own time, then he starts understanding everything. Before that, even if God tells you, you will still doubt. Just like everything becomes right as soon as the right time comes, and similarly, when right time comes, you will start understanding it yourself. So this is a personal path of every person.
