So much work to have the truth

One, can i say how proud of my group I am? Like, we are so doing our part individually making it easier for everyone else in the group. I think a group who is willing to do their part will work out and do a great job.
Alright so when I first read the list of everything that was needed for the frankendraft and finished work, I wondered "Is all of this necessary?" Yes we need all of the background information and the "before, during and after", the major players and all of that but is there an extent where it is just paraphrasing? I often feel like I am reguritating facts with some of this work, minus the beliefs and motivations as most would not know them but sometimes I am like is this going to go over all the reader's heads? How do I make it intriguing and easy to follow without being too much? It is taking alot to keep the focus narrow but I think we are nailing it on the head.
Finally it is a ridiculous task to state for facts what is someone's or some group of people's beliefs as how can we know for sure. I find it beyond challenging to say "this is what they believed in" because honestly, every single person in a group sees an idea differently and wants different aspects of an idea. I want to be able to say for sure what people believe in but I don't think even those people know what they believe in. I do not know if I am making this more complicated that what it has to be or if it really is that complicated.
With all this information and all these voices im just overwhelmed.
