Since I have never been satisfied with the myriad of answers this society has invented to curve their fears about this existence, I am going to add a complete new one for you to love, hate or terrify you.
What if the reason we are here is primarily a form of correction. But it wasn't the creator who sent you here to live out your physical sentence, it was you. Now this idea may sound ridiculous on many levels when reasoning out your starting point began when you were born. What if you never had a starting point, you did have a permanent existence already, belonging to a vast community of other immortal beings who alongside with the creator are creationists. It could be that when you are designing new realities/universes/dimensions/ you don't know as much of the process as the source creator itself, so if you create a design flaw the only way to correct your error is to sample your mistake. This universe being the ground that the source creator designed for us to correct any anomalies we create in our primary existence.
But then this is just an idea, another invented idea.
