Why are there copying errors in the bible

Your sky daddy being omnipotent, as they are, could have easily made sure that your bible got copied each time without errors. Imagine that everytime some scribe was about to make a copying error their pen broke or it temporarily stopped working. That way the scribe would know to check what they were copying again. Or suppose you sky daddy corrected there copied version when nobody was looking. Or why didnt your skydaddy send a photocopier down from heaven so that the disciples could copy their gospels? I mean, giving the disciples the gift of a photocopier would be far more practicle than giving them the gift of the holy spirit who doesnt even exist. Clearly they could have guaranteed that the bible went down from generation to generation without any copying errors.

And so it might come as suprise to some xians that the bible does infact have billions of copying errors - more errors than there are words in the bible.
