I don't know much about the bible but I know that it consists of many different authors.
Yes it does.  Many of Jesus's disciples wrote parts of the Bible
Yes, that is true. Many Christians and Jews consider it to be a product of divine inspiration and record of the relationship between God and humans.
And the Bible is the best selling book of all time
Yes, I have heard that before. Most likely because Christians buy it a lot. Also Jews buy it too because the New Testament is a collection of writing by early Jewish disciples of Christ, who wrote it first in Koine Greek.
And the Bible is the most translated book in the world. 
Never heard of that before but it sounds believable. Most Christians who read the bible refer to Jesus a lot who is a carpenter and Jewish preacher/religious leader.
