It really depends on the application of knowledge.
I have a qualification as a civil engineer. It required knowledge in civil design, but that depends on what field in civil engineering that I'd want to pursue, such as structural design, road work, in water work (like water pipe or sewerage system), etc. I would needs some basics, like maths and physics that are related to these fields.
None of the subjects require me to know any specific religion, any specific deity, or read any specific scripture or related religious literature. The bible and Qur'an are both utterly worthless, because they couldn't help me to study or graduate in the fields of civil engineering.
I had also computer science qualification and no scriptures can help me with knowledge in programming, algorithms, database design or administration, networking and a whole lot of other stuffs.
Likewise, if I want to learn about religion, I would read their scriptures...that if they have any. I wouldn't attempt to use engineering or computer science textbooks to find out something about religion or god(s).
And one thing for certain, the sources of knowledge in civil engineering or computer science didn't come from god, if that's what you are suggesting.
Each knowledge have their uses, applications and limitations (or scope), and often they are not interchangeable.
And over the years, I have acquired many different knowledges, that are unrelated to computers, engineering and religion/mythology.
So what specific knowledge are talking about?
