Size – the easiest way to create the illusion of space. Objects farther away will appear smaller.
In another hand, as Bertrand Russell once said, “Sir Isaac Newton was very much smaller than a hippopotamus, but we do not on that account value him less.” :)

So, Newton’s law of universal gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Today we still use Newton’s formula and force it into all our calculations even though we know it is wrong…
Whereas it is what is holding us back, it is not what holds us to the Earth.

Overlapping – things that are closer to us may overlap those that are farther away.
But… it is clearly superior to Newtonian gravity, being consistent with special theory of relativity! :)
Besides, in the words of Winston Churchill, “The farther backward you can look, the farther forward you can see.”
