I read a book titled “The Skeptics Guide to the Universe”
It taught me that everyone has some beliefs that are part of their identity. For my Mom (and likely your Dad) God is a core belief that is unwavering. Because of that and their beliefs God made everything they can’t just believe in evolution fully.
My Mom believes evolution happens in everything but humans didn’t come from apes. This is the steps she won’t cross because it violates her core beliefs. I gave up on her knowing about evolution. Why does it really matter anyway is what I told myself.
I do teach both my kids about evolution and we have gone to the natural history museum in DC and talked about the human evolution section. All you can do is worry about the next generation. Talk to your friends about it. Good luck.
