Upon further research and inquiry, evidence has been presented to further the explaination of gravity of which is not a force unto itself or even a force caused by or inherently present in bodies that have mass, but rather is just one of the effects of the warping of space-time. "Bodies that have mass are the cause of gravity" is a commonly held misconception. It is in fact bodies with "energy" that can cause the warpation of space-time - this includes Earth and even photons. This statement does mean that bodies with mass can cause the curvature of space-time (i.e. "E=mc²"), but Newton's approximation of gravity ("F = GMm/R²") excludes light.
To understand this concept better, let us visualize two bodies in space with one being much larger than the other one. The larger body - l - energy causes a warpation in space-time that in turn causes the smaller body - s - to follow this curver path. Depending on the degree of deviation (how much the body curverd space-time), s will or will not make contact with l, but s's velocity will have been changed by l. Gravity cannot be observed unless their are at least two bodies - l and s - present in the system. The best representation of this would be the science demonstrations done across the world in science museums. A bowling ball is placed on a trampoline which causes the trampoline's fabric to warp. Marbles are then placed on the trampoline and proceed to rotate around the bowling ball until they come to a stop - always "attracted" to the bowling ball. The bodies or their masses did not cause the attraction between them - it was in fact the warped trampoline fabric.
Another way to imagine this would be to picture only one body - l - in existence in the the entirety of the Universe. L causes the the warping of space-time, but becuase their is no other body to interact with the curverd space-time, gravity is not observed non-objectively. Upon revisiting the trampoline-bowling ball analogy, the bowling ball causes a warpation of space-time, but without any marbles, gravity is not observed non-objectively.
To put simply, bodies with energy cause the curvature of space-time, which in turn creates the effect we perceive as gravity. Bodies with mass can be the cause of gravity, but do so indirectly.
