But, my point at that time is that the God who said all of those things would be quite a trickster to say them if they were lies.
Again, you have no proof the Almighty uttered those things. You simply have a book claiming such. Greek mythology has the Gods making many comments, but you don't see anyone going around claiming that Zeus must exist because we have documents citing those utterances. Don't get me wrong, I'm a church-going Catholic and I understand that some things must be taken on faith; however one must be rational when determining what may or may not be taught in public schools, and a faith-based curriculum is not necessarily rational.
