This is an interesting topic.  I apologise, but I haven't listened to any of your fathers' talks (I don't have a sound card on my computer here).  However, there are many scientific arguments for evolution too:

Just recently, an interesting situation was witnessed in a laboratory, where a strain of E.coli was seen evolving new and beneficial characteristics:

I think that one interesting point on this whole issue is that one side (evolutionists) took discoveries and ideas and built a non-theistic theory around it, while the other side (creationists) already have an theistic explanation and then reconcile scientific discoveries into it.  Both require a degree of faith, but it depends upon whether one favours faith in God, or faith in human reason.  Exciting stuff!

There are several as last I remembered. But alas- websites die.

Talkorigins.org pretty much has creationism sufficiently answered on every front I can think of:
