To THEISTS: Why do you think god created humans?

And an answer like 'because he loves man'. That does not answer the question. There needed to be a motive for your god to create human beings. And if he really was omniscient, wouldn't he be able to forsee death, destruction, hate, and non-belief? If his intentions were to have it so that in order to appreciate his love he would devise a plan to make all imperfect, why didn't he just created humans imperfect from the get-go instead of having the fall occur?
