What about this ?

"o mankind! we created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise (each other). verily the most honored of you in the sight of Allah is (he who is) the most righteous of you. and Allah has full knowledge and is well acquainted (with all things)." The Holy Qur'an (49:13)

I read in the Bible about how God "changed" our speech and sent us out to go our different ways. I think there was a reason behind it then, which remains here now. Without our mix of cultures, beliefs and religions we would never become "as one" with God. The different climates in these regions is why and how our differnt races have came about. Often I wonder if we would have had more peace in this world if we had all stayed with our same culture.

God created man to understand group by recognizing other! Societies break down into groups because its what they can understand. Nationalism and group identity strengthen in the presence of an enemy. Regardless of who or what created man, man will always break off into factions. Therefore, my god is okay with this, as he understands this is what he gave us to work with!

you see, we might be different in our beliefs, skin color and etc. but deep inside, we share the same emotions and we work together indirectly. everyone of different countries, religion, cast are joined together through this invisible links. such as work, common interest and also love.ever see the marriage if people of 2 different races? love bought them together. yeah it is true that we divide ourselves into different groups. yet there will still be links, bonding all of us as a whole.
