ishqia, thanks for participating. But the Q is why to create all those things. Why to creat human and then test them? why not creat ideal human?

well, soul exists. and it has engraved memory of pasts. But because it has come to this body form it has forgotton the past. if by some means we can read those engraving on the soul we can remember past also. (Thus if we refer some news the person remembering the past; this could be the logic)
