prophets around the world

[Maey]

i have a question and i hope someone can answer it if possible.

At the time of when religions were still being taught by prophets.. were prophets only in the "Geziret El Arab" the middle east now? were there any prophets sent to places like europe / china etc..?

I know that Chritianity was the dominating religion of "Al Room" Like Ceaser etc..

or was religion to these places spread after the existence of prophets.

Also any thing in the Qura'an that specifies why prophets were only in the Middle Eeast?

thanks
