Peace Sarah,
Quran, Torah , Injil all based in middle east. In fact Bible came from Arabia.
All the messengers mentioned in Quran are from the same area since the primary addressee of the Quran was the people of Arabia. But that does not mean God did not send messengers to other parts of the world. God has sent messenger to every nation. They were just not mentioned in Quran.
10:47 For every nation is a messenger; so when their messenger comes, the matter is decreed between them with justice, and they are not wronged.
16:36 And We have sent a messenger to every nation: "You shall serve God and avoid evil." Some of them were guided by God, and some of them deserved to be misguided. So travel the earth, and see how the punishment was of those who denied.
40:78 And We have sent messengers prior to you. Some of them We have told to you, and some We did not tell to you. And it was not given to any messenger that he should bring a sign except with the permission of God. So, when the judgment of God is issued, the matter is decided with the truth, and the followers of falsehood will be lost.
