Secular author proves why God is real

I found this in my "Social Thought into the Twenty First Century" book.

"Let us begin by establishing two fundamental and realistic principles. The first of these is that social influences, though not directly observable, produce observable effects. We cannot, for example, directly observe those ideas and involvements that lead people into wars, but we can observe the aftermath of a bombing raid. We can say, then, that even though social forces remain hidden, they are nonetheless "real." They are real because they are real in their effects. If the invisibility of social forces appears to deny validity to the efforts of social scientists, the real consequences of social inolvement gives their work a scientific justification." 

Umm, this secular author just proved why God can be invisible but yet real at the same time. The effects of His existance are evident in all of His creation.  I won't say much more, take a second to really take it in.
