What you need first is to sort out truth in your own mind and move to the middle of the argument to become credible. The ID guys have issues but they are not all wrong.
There are issues on both sides of the arguments and you need to be in a position to discuss them objectively.
This is very tricky because we all have biases and tend to move from one extreme to another. I struggle with this challenge. If you try to come from the position that evolution or universal common descent is fact then you will be vulnerable to losing credibility as there are issues with the theory. The theory can be less than completely factual and still be a very useful part of biological sciences.
Again the real issue is not whether evolution is true or false or somewhere in between, it is making sure she learns to think critically. The problem with the young earth position is it does not take into account that what is consistent with the bible is its theology which can be brought forth with the combination of story and history.
Maybe the place to start the conversation is around imagery in the bible. The serpent in genesis 3:15 appears to be imagery of evil (satan).
If this is true what else could be imagery. A day or Yom in Hebrew can also mean a period of time. Peter said in his letters that a day to God was like a thousand years.
