Does the over explanation answer a question if it is not actually answering the question?
The idea of researching the Biblical accounts from a different point of view does the same. It never answers anything but just gives a new explanation for something which has already been there. It never gives one direction but obfuscate one thing after the other to keep it as opaque as possible.
This book does the same job. It quotes from different sources with varying explanations but always fall short of what it wants to establish.
It is difficult for an author to keep the things straight and say the things they want to say without committing to an idea. Without that its a lot of research which just enriches your vocabulary on the topic without any answers.
