I'm planning on taking my kids to the dinosaur exhibit at the local zoo. One of their favorite shows is "Dinosaur Train" on PBS kids. I approach evolution the same way I do other science subjects I have issues with such as global warming. (BTW, I've noticed a lot of libertarian atheists and agnostics reject climate "science". Where do you fall on that?) Anyway I let them take in the information, then when they have questions I explain what the "science" teaches and where I disagree and the scientific and/or religious reasons for my disagreement. Just because some people of faith have a hard time striking that balance doesn't mean it's not there.
As far as climate science goes, I'm open to all theories. It's just hard to get the truth with so many political agendas clouding things up. Pun intended.
