As the distance from the planet is doubled, so the force of gravity must spread out over four times the area. This is why r is to the power 2. (It squares). If the universe were twodimensional (a flat plane), then, when the distance from the body doubled, the force of gravity would spread out over twice the space. (r would not be squared) 
But as our universe is threedimensional, the force of gravity decreases by nine times when we are three times further away. This is why the variable ‘r’ is the denominator (at the bottom) and is squared: Because the force of gravity must be divided and get smaller exponentially the further away we get from the source of the gravity. 
But we take it for granted the distribution is perfect in either system. Why could gravity not be something like g=m/r^2.0000000000001 ? Such would constitute a difference of a thousandth of a mm for every light year. We would never notice it. But we take it on faith that the fraction is not there. We just know it is not so.

Gravitational Waves & General Relativity A computational analysis of the theory of gravitational waves; as expressed within Einstein’s Theory of General Relativity and the wider realm of Astrophysics. Essentially a critique, this study has been written for the purpose of explaining the unobvious challenges faced in building graphically dynamic evolutionary computer models. These models compute the theoretical functionality of gravitational waves in the celestial paradigms of solar system formation and galaxy formation. 
The likelihood of circular orbits, given gravity and chance, are much the same regardless of the gravitational exponent. Even nearcircular orbits are rare. Consider how much less like a solar system this would be if it were in three dimensions. Here are many bodies programmed using g=m/r^2, but with random starting points and no force of spin: 
What this shows is that the very essence of design, of form, of the universe itself, is intrinsically conscious; because without consciousness there can be no design, for consciousness is a necessary feature of design. As the Universe is clearly designed, consciousness must be at the root of it. This is termed Teleology. That the physical universe has an end point, a goal, and that all the laws of nature, known and unknown, are deliberately directed towards this final construct. 
This animation shows that in order for a solar system to form, the planets must have started from a position of spin or else the planets in the solar system would not have uniform orbits. A star already in a uniform orbit going nova dictates the starting positions of the planets.

A similar program was used to demonstrate how and why the Moon slowly recedes from the Earth. The gravity of the Sun is gently tugging on the Moon at 4cm per year.

How birds and other flying phenomenon defy gravity: Principles of Flight 
The undeniable point being that in order to get anything to work properly, regardless of whether it is a solar system, galaxy, lifeform, or flying machine, it would need to be deliberately and perfectly designed to do so. But a more subtle point implied in this, is that we need to have Cartesian Dualism as an intrinsic and fundamental feature of the system in question. Design implies that the perspective of design stands outside from that which is being designed. The blueprint for the design of a house cannot be part of the house itself. The blueprint must be external to the house. Similarly, if the blueprint of an object were intrinsically and completely inside the object being designed it would need to have existed in its pure form before it manifested in its physical form, which means that its true form would have to be a priori to its physical form. Thus the underlying reality of the physical world is a construct like the shadows on the wall of Plato’s cave. 
If this is all a bit much to try and absorb at once, it would be s good idea to buy the book. These ideas are better discussed in the logical progression outlayed in print format. There are many more diagrams and countless new designs for weird and wonderful aircraft in the book.
