This is not any kind of helpful tips or hints on this kind of debate. But allow me to chime in. I'm an individual that has a recent college biology degree that I earned really just for personal enrichment as I'm +60 and not looking for a new job. What happened was I took a college algebra class and next thing I know I'm taking college level organic chemistry and biology in the evenings and weekends and to keep going I had to declare a major so I settled on biology as that was the path of least resistance.
Anyway, for most people, smart as they are and on either side of this debate there is actually little understanding of "evolution" and what modern evolution actually teaches. So OP, not to insult you, but you probably know as much as the person you are debating, which is probably not very much. This is not again an insult, it is just my observation.
If you were having this debate with someone that is actually informed on both modern biology and chemistry and that person knew you were also informed and couldn't fool you by being less than truthful, your job convincing that person that the Bible offers up a logical and much more elegant explanation of life as we know it is actually easier. You still have to contend with the fact that evolution is at it's core a faith, a religious faith, so you still have that to deal with. And the more you study modern evolution, the more you can see where it is actually a "faith".
As I feel that I have a fairly good grasp of basic evolution as it is taught at the undergraduate level, about as far as I go when evolution (and carbon dating) comes up is to state that creation as in the book of Genesis requires but 1 miracle, evolution requires miracle on top of miracle and none of these are observable today. If vertebrates have been on the earth for millions of years there should be bone fossils galore and for what reason should a thinking person believe that an entire extinct species of prehistoric man be considered real based on one piece of a jawbone found in a cave in rural France?
All we can do, both inside and outside the theory of evolution is hold forth the gospel of Christ Crucified and leave the rest to our Savior.
Much of what is called "evolution" is actually naturalistic selective breeding, it's not an actual species jump.
