Oh, I believe it's too late for your dad, my good friend. I am unaware of his age, but I hardly think it matters, judging by your conversation. He's already in that close-minded, cannot-be-persuaded state of mind, in which many creationists of the earlier generations find themselves. No amount of emperical evidence and logic, can disentangle them from this web of willful ignorance and self-deceit. It is unfortunate, yet I would advise you to not bother, and just live and let be.
Of course, if that does not satisfy you (as I suppose it wouldn't), you could always ask him to acompany you to your local Natural History Museum. If he were to refuse, then you could always counter him with the 'You've got nothing to lose', or it's Scottish counterpart 'Only a true man can wear a skirt!(kilt)' argument, which is basically telling him, that if he truly believes in what he believes, and that if he is so confident in his faith, then a trip to the museum shouldn't be able to shake it up, on the contrary, it would re-affirm it. Then, once you have him in your grasp, you can easily display to him, the many evidence supporting evoultion, which are clearly explained. If you're lucky, they'll have one of their screenings, usually regarding evolution, so you might one to sit through that, as well.
This doesn't guarantee success; however, it is sure to place a small doubt in the back of his mind, next time you try to argue. Good luck, and hope that helps.
