It looks like we are at in impasse. You say the fundamental forces are a proven fact. I suppose in a sense, they are. But you do not know why or how they exist. You do not know what causes them to exist. You can say that they are simply properties of matter, but you cannot tell me why. I say they exist because God exists. Without an explanation for their existence, you might as well just call them God. At this point you are simply making an observation that something consistent is happening, and you don't know why. So you've given it the name Fundamental Forces. People experience God. I experience God, but I don't know why or how God exists. You believe fundamental forces exist because you experience them. I believe God exists because I experience Him.
Here is an example of what I am saying. If I drop my coffee cup from some elevation above the floor, I see it will fall to the floor. Simplistically, for the purpose of this example, the definition of gravity is stuff falls to the floor. When we use a definition, what we are doing is replacing a lengthy phrase with a single word which means the same thing. So we might ask, why does stuff fall to the floor? You would say, well, stuff falls to the floor because of gravity. In other words, all you are saying is that stuff falls to the floor because stuff falls to the floor. You have no explanation. These forces you are referring to are nothing but a simplified version of an observation, not an explanation at all. Why? Because you don't know why.
