Peace to you too.
That's very easy to explain, and the scientists can explain it in more certain terms than I can, but let me tell you exactly how it works.
We all come from the same group of people, so essentially there should be NO differences between us, right? Well, of course, that small group grew and then travelled and split up and ended up inhabiting most of the planet as what today we call the human race. So how did we all end up so different looking?
The skin colour differences are easy to explain (the temperature and weather conditions in the places where our more recent ancestors settled). Then, I hear you asking, what about height differences, bone structure differences, facial feature differences, that can be observed, some of which are more typical to some skin colours or parts of the world than others.
The answer is *the same kind of thing*
As the first group split up and spread out, it was exposed to not only different climates and temperatures (which explained the skin colour), but also to different environments and different challenges. Human beings, even from one generation to the next, and especially over hundreds and thousands of years, adapt. Just as our various skin colours were "adapted" to fit the temperature and climate, our facial features, our body types, all of the differences you point to... evolved in us as we adapted to our various surroundings. So people in West Africa developed certain things, whereas people in South East Asia developed others, and so on and so forth. So every single physical difference, every common trait between what we now foolishly call "different races", from skin colour to everything else... was just that BRANCH of the human race, somewhere in the past, ADAPTING to whatever environment they were in.
So as I said - we are all EXACTLY the same. You can think of racial differences like skills. One of us is black, one is white, one is latino. Just as one of us is a butcher, one is a baker, and one is a candlestick maker. Originally we were all babies, and then we were all just **** in school. Exactly the same. Then we went our separate ways and learned different jobs and different ways of life and now we are very different - but we have far more in common than we have different. All of the differences, we picked up along the way, from adapting to whatever environment we were in. But our similarities are far more profound: we are FROM the same region, we are from the same race, we are from the same skin colour and the same facial features - our differences NOW are just ***** ADAPTATIONS that helped us along the way - END OF STORY.
And this is not just a theory. This is proven and universally agreed upon scientific fact. All the evidence has been presented a thousand times. It goes against mainstream religion and all racist ideologies, but it is fact. Ask any expert. It's exactly as much of a fact as the fact that we evolved from apes, and the fact that we need oxygen to survive.
Sincerely and with peace
