Furthermore, how can one manage to write everything about another person, even his darkest secrets in the bible when the author is not that person?

2) How did the people from the past know how they were "created" and wrote it down in the book of genesis? Who wrote the book of genesis? Is it adam or eve?

3) Are there passages or books that contridict each other?
I assumed that the qoutes with " " in the bible are words from God. If so, does that mean that the qoutes are divine, true and do not contridict, while the rest of the bible- we have to read it with care?

Please state whether you are a christian or non-christian. If possible, please include the source where you get your information from.

Thank You.
