When i looked at my whole family members perfunctorily, suddenly I remembered what my teacher ever said to me, "God create people face in any various shape and color. None of them is perfectly similar to each others. It shows us that God has been being the most perfectly amazing creator in the world with His great Kunfayakun," more or less. Except how people can have any different face from each others, I also realize something arousing my curiousity. It is obviously true that God is perfectly amazing creator in the world and create human face without perfecly similar to each others, I don't deny it. However, His works is not merely KUN FAYAKUN LANGSUNG DADI. There is something undoubtly works into it. So I try to figure it out by using my logical method.
Let's make analogy. Every person has different mixed colors composition. Color Blue X=person X, Color Yellow Y=person Y. If person X marry person Y, then they will have kiddos with Color Green XY1, Color Green XY2, etc. The kiddos will be similar to each others but they still have the different looks (look the number of XY1,2,3). It looks like Color Blue and Color Yellow are blending one another. So every kiddos also has mixed colors composition. As if we mix the Color Blue and Color Yellow on water color pallete for twice or third times or more at different times. So every outcomes doesn't really similar to the result which we mix it every single times. It depends on the composition matter. How much volume and how strong the blue and the yellow are mixing one another.
Then their every kiddos will marry person C or person D or person H or person E or none of them. And they will have any babies with any mixed colors complection again, the example are Brown CD1, Brown EH2, etc. The change process will bulit its mixed colors composition gradually and continually. Just imagine pohon faktor or silsilah keluarga if you can't understand my explanation. It has plentiful of mixed colors composition, so the process and the outcome are like blending colors composition in water color pallete.
In other words, God works on the people face matter by mixing colors composition in genetics method. Do you get my explanation? I don't think so. Don't take it too serious, dude. I am just soliluquizing.
