Book Structuring Expert Needed for Psychology and Religion Non-Fiction

I have a story to tell: - It starts with redifining the ages of development. - It moves on to explain ancient religions and myths. - It sets out a psycological and religious evolution over time. - It covers the Abrahamic as a way to detach people from religion. I have already written it and is about 90 pages long. However, especially the part about religion, is very confusing and not very well structured. I'm looking for someone that will review the book and help me to structure it in a way that is less confusing and easier to understand. I'm pretty good at explaning everything I have to say, just putting it into words I struggle a bit. Please tell me your religion and, from 1 to 5, how important it is for you.
