Hey, fork.
(Welcome to EvC) A lot of your success with your friend will depend on your motives in the debate with them. If you simply want to find facts or information so that you can say that
I'm smart, and you are ignorant! you will perhaps win the argument yet lose your friend as they retreat into the zany world of the creationists! I believe in God and I believe that God imagined/created me and all that is long before I or my species was evolved enough to even consider Him.
However...
God gave us brains. We don't have to simply listen to every creationist argument out there! One won't go to "hell" for allowing for the possibility that God and Science can comfortably co-exist.
Dr. Kent Hovind is not helping Science or Religion, IMHO.
He is causing a battle between two sides that could be in agreement! One can be a perfectly logical and disciplined student without insulting or alienating their Creator!
God is a Belief. How sound that belief is rests on the individual, not on science. God does not have to be proven.
Have your friend look into Kent Hovinds background from the viewpoint of his skeptics. Reassure your friend that although Hovind may be wrong on many if not most things does not detract from the validity of a belief in a Creator!
You wanna make bridges rather than burn them, right?
