Mathematical Symbols: How the human language is created. Creating the mathematical symbols is the point where the human spoken language started. I wrote spoken language, not written language. Human language is based on mathematical-geometrical symbols. For example, the number one symbol is not just number one but it is also, one of the its directions, it is the concept of "simple" on it, not complicated because it is just a line. And they created the word "simple" only saying "as I is" , or ""I" is", combining with the other mathematical-geometrical symbols they created before. And there are more linguistic-mathematics direction on that symbol. When they put two lines together to "y" symbol they created at the same time the number 2 concept and the number 2 word. So, the primitive number 2 was just an "y". Later they created more adding more mathematical concepts like "T", not this "T" but Etrus
