To use the error of a Sunday School teacher to say that Genesis isn't true is a false argument. (I had a teacher once say that blacks were meant to be slaves of whites according to the Bible). I NEVER said Genesis was not true! Why do "Christians" always keep making things up (falsifying) when discussing evolution and the Bible?
The teacher. Part of the church?
The teacher is a human being, prone to sin and error. To use a teacher's mistake to bolster your argument is fallacious.
And may I modify what I said about your interpretation of Genesis. You believe only parts of it.
