Witnessing Tools for Evolutionist

[supertone]

Hi team, does anyone have any references or links that I can share with a friend of mine that I've been witnessing to. He is a medical doctor who has studied genetics etc... and is adament that creation is false and that evolution must be true.

Most of the dialogue he uses is above my station of understanding so I can't answer his questions appropriately. I'm keeping my message simple but has as before, any literature you know of would be fantastic.
