As a physiscist, I think that the strongest rational argument for God's existence is the mathematical representability of the natural laws. Science has proved that natural phenomena can be predicted through some specific mathematical equations, the laws of physics.
The fact that through a system of mathematical equations it is possible to predict sistematically the results of all mechanical, chemical, electromagnetic, optical and thermal processes makes it unreasonable to suppose that nature hasn't an intrinsic mathematical, and therefore rational, structure. There is in fact no reason to expect that a non-mathematically structured universe could be sistematically described by a system of mathematical equations. Actually the first scientists (Galileo and Newton) who began to use mathematical equations to express the natural laws, were christians and they justified their choice because they believed that the universe was a creation of an intelligent God. Their intuition has certainly revealed one of the most fruitful intuitions in history and all scientists now accept the idea that the natural laws can be expressed through matemathical equations, even if some of them (atheists and agnostics) seem not to understand the theological implications of this fact.
I would like to point out that a mathematical equation cannot exist by itself because it is an abstract concept and it may exist only as a thought in a conscious and intelligent mind.
The insurmountable problem for atheists is to explain the existence of the laws of physics and their intrinsic conceptual and mathematical nature.
Usually atheists refer to the natural laws as "patterns or regularities" (or equivalent expressions) but these are only vague and empty rethoric figures, without any real meaning. The point is that all modern physics, and in particular quantum mechanics, consists of abstract mathematical models without any concrete representations.
In conclusion, the existence of this mathematically structured universe does imply the existence of an intelliogent and conscious God; this universe cannot exist by itself, but it can exist only if there is a conscious and inteligent God conceiving it according to some specific mathematical equations.
