They can't even grasp the concept that animals literally can not make protein
That doesn't sound right. Animals certainly make protein. Humans can't adequately synthesize all the types of amino acids they need, and have to get those by breaking down protein consumed from animals that can synthesize those amino acids, or via certain specific vegetables (beans are a good source of lysine).
DNA is essentially a chemical instruction book for how to synthesize various proteins. Any organism that employs DNA is making its own protein...
