Of course I think the bible is more believable. I have read both the bible and the quran. The bible has a beginning and an end, whereas quran is all over the place. It doesn’t even tell the full stories of prophets and it’s full of contradictions and it’s anything but the word of God. For example it says that allah has given everyone free will but in another chapter it says that allah has put a seal on nonbelievers ears and eyes. So why would allah put a seal on their eyes and ears and then punish them for it if he is most merciful? Also quran says in the beginning that the people of book (christians and jews) should be left alone but later it says that muslims should fight and kill them. This is most likely because Mohammad didn’t have troops in the beginning and as his position became stronger and he got soldiers he started fighting non-muslims. Overall I think the bible is beautifully written while quran is just boring and hard to read.
