The Earth Planet and its Mankind, is a Sea of different Fish species living together in one Hub. There are different Races of mankind on the planet with different cultures, opinions, values beliefs and so on, but yet we co-exist together. It is a system (a set of related components working together to achieve a goal.) in that every race of mankind needs each other in a certain way in order to survive. We may not agree on all the things and each racial grouping may have a different opinion on certain things, but still we try and make a level playing field where every race is satisfied and hold on to their opinions and beliefs so as to avoid any resent and animosity toward each other. But still this does not mean that there is no animosity among mankind on this planet. There is indeed animosity as each race of Mankind wants to have control on certain affairs of the planet. However since mankind functions like system who needs each other to survive, therefore this animosity does not usually escalate to something more severe. Just like in the sea where specific fish species are only found in a specific territory within which they are in abundance, so is mankind on this planet. Each particular racial grouping of mankind is found in a specific territory where there are in abundance. But because we live in one hub which is planet Earth, hence all racial groupings can be found almost in every territory of the Planet. The only difference of course is, they are territories where a specific racial groupings of mankind exists as a majority while other groupings are there as minorities. These territories also have conditions and climate that these indigenous racial groupings are acclimatized to. However still almost every territory on earth can be inhabited by every racial grouping no matter the condition and climate. This is so saying because mankind has evolved in terms of technology and research to withstand almost every climatic condition on the earth planet. We have positioned ourselves by investing time and energy in areas of innovation, technology research and indeed economy for future survival through shared knowledge. Not every racial grouping is intelligent and innovative enough to advance on their own, but still those races that are innovative passes down whatever new technology they may have acquired or any invention they may have come up to other races for the betterment of everyone. How mankind came on this (Earth) planet or where we came from, is still a question. However because of the same racial diversity and having different opinions, values and beliefs, so many answers have come up, as to why we exist as humans on this (Earth) Planet. Some point to God as our creator others say its evolution while some simply say it's just nature Nevertheless and whatever the case may be the most important thing for every mankind is that we are existing and henceforth each racial grouping of mankind will continue to exist as long as Planet earth continues to exist and support human life.
