Why Would The Quran Mention All OF These Prophets?

I can understand why atheists do not believe in Quran. They think all the ideas of religions are hoax. In other places in my blog I debated them. The thing I could not understand why still many Christians and Jews do not believe in the Quran. There is no compulsion in religion. However why Muhammad (PBUH) would mention all these prophets of the old and new testaments if Quran was not from God. Why he would mention himself only 4 times. Who in human history brought a book like the Quran and mentioned all of these prophets like did the Bible. If I would say today I am a prophet people will put me under the microscope, they will investigate my family and people who knew me to see if I am a liar or crazy. They will likely dig in my life to find things against me. People will look to me with great suspicion unless I can dramatically convince them. The responsibility lies in people in the top of the religions to do their homework since they are the one who will answer to God in the day of judgement. Quran 3:70 O followers of earlier revelation! Why do you deny the truth of God's messages to which you yourselves bear witness?
