I had a similar experience but with a book about Dinosaurs that contained scientifically accurate eons, etc.

I started to piece together that while we might not be 100% correct all the time, YEC doesn't even have an alternative. They just try and debunk evolution but have no scientific method/knowledge that proves they're correct.

Where's all the geological science that shows a 6000 year old earth? None. There should be competing theories, but instead it's just "you're wrong, trust me bro."
