I see the examples of gravity as the bending of spacetime with a planet orbiting the sun.

But how does that work for the gravity that keeps me on the surface of the earth?

It is exactly the same in both cases. The Earth is falling towards the Sun (but never gets closer because it is moving sideways). You are falling towards the Earth (but are stopped by the ground).

In both cases, the apparent force is caused by the curvature of spacetime. The best analogy I know is: Imagine two people who are a mile apart and walking in the same direction, North for example. You would expect them to stay the same distance apart unless some sort of force pushed them together. And if they were on a flat surface, that would be true.

But lets say they are on the surface of the Earth, a few miles from the North Pole. They are still both heading north but they get closer together as they approach the the North Pole. This is not because anything is pushing them together but just because of the geometry of the curved surface.

(In this analogy, the lines of longitude are 'time' and so the North Pole is in the walkers' future)

Perhaps within a moment in time the same photon occupies both a temporal and spacial position which nature attempts to unify and so an attractive force is manifested to create spacetime as the universe splits at light speed into absolute space and absolute time

Pseudoscience and nonsense. Space and time are not absolute.
