Found these for 1-5$ each at my local book store- which should I read first?

I always go meander my local bookstore to see what they have. It’s one of those super old shops that’s been around for 60+ years and just has stacks of books piled to the ceiling – mostly used. They have a great selection of old books. These each were 1-5$ and I couldn’t say no. But I want to read them all at once lol. I am a believer but not a very well studied one. Just always subscribed to the belief there are definitley aliens and the things we’ve been told about our history are lies.

Fun fact I also learned from these: Dr J Allen Hynek started the Center for UFO Studies in my town!
