Fiction. Just like the Koran and Jewish OT, Buddha and Hindu Vedas. They all have real histories in that people invented them and buy into them still. But fiction in that they were all human inventions started in an age of scientific ignorance.
I really warn against focusing on one religion. Our species was around long before any written religion or boarders. Our species merely gap filled and made very bad guesses as to the nature of reality and those lead to our species creating religions and god claims.
I do think it is important to read about all religions and compare their histories. I think the more religions you learn about and compare the more you realize the arguments simply have different names and details but the arguments over morality and good and bad are the same motif in the end. All want to claim their club is the source of morality and has the answers to our meaning.
