A simple challenge for atheists

[robvalue]

1) Rule 2 does not apply to anything I label "God", but to everything else.
2) Everything that exists has a cause.
3) The universe exists.
4) Therefor, the universe has a cause. Let's call that cause God. God does not need a cause (see rule 1).
5) I have a story book that my mummy and daddy read to me as a child, told me it was true, and has a character called God in it.
6) Mummy and daddy can't lie to me.
7) Therefor, the christian God exists and created the universe, and wrote my story book, and everything that happened in the story book is true. If reality contradicts my story book, reality is false.
8) If it is not convenient for something in the bible to be true for a given argument, then it is a mistranslation, or needs interpreting to mean the opposite, just for as long as the argument is being made. Then it goes back to being true again.
