Stationary in reference to what fixed point?

Actually to say that an object is stationary relative to its initial position is to assume that there exists an absolute reference frame, which has been irrefutibly proven to NOT exist.

During Newton's time, people thought that space and time is absolute, and that space is filled with a substance called ether, which allows light to propagate. All motion in the universe can also be measured relative to this ether as the default reference frame.

All efforts to find this ether has failed and we also now know that light can propagate through space without a medium, and also Einstein's Theory of Special Relativity has undeniably shown that all motion are relative. So the concept of being "stationary" requires one to specify relative to what reference frame is the object appearing to be stationary.

So the statement that the object is stationary relative to its initial position is meaningless because (1) the statement implies that the object has moved therefore it cannot be stationary, and (2) an object always appears stationary to itself (assuming that the motion is under constant velocity, no acceleration).

The answer to your question depends on how you observe and comprehend. The cognizing mind perceives objects in Space (thick,thin,flat or deep etc.) through vision and relates actions to Time (stationary, moving fast or slow etc.). All these actions are relativistic with the cognizing consciousness sampling the dimensions of space and time simultaneously and comprehending the results mentally. The idea of dimensions and numbers originates related to objects located in space and that of actions concerning objects being static or moving,growing or diminishing related to time and the overall integrated observation addressing human comprehension. A small plum on the palm can be seen instantly but a large stadium takes several seconds. The overall observation is therefore depends on the vantage point such as standing on a hill we can see the panorama of a city while sitting in a room only the ceiling! Hence also the answer to the question. If we fix our observation only to terrestial ground all static objects are seen stationary and moving objects relatively as railway travel experience. Observing from a space ship the static objects on ground appear as an earth globe rotating lock stock and all.

"stationary" is simply a term that requires a relationship to something else. Stationary to what? The earth rotates but the sun also spins around the galaxy which dances in orbits around other galaxies and the whole thing flys apart from some distant center .... nothing is ever really "stationary" ....

Stationary on the Earth's surface, yes. Stationary in the Galaxy/Universe, no.

No object is stationary, because it is constantly moving through space and time, therefore if you stand perfectly still, gravity, the earth's rotation, or something else will move you, and you will keep moving until the end of time.

we can't feel the earth moving no matter what, because of it's massive size and it's rotating speed.

All objects which are not in motion with respect to earth are STATIONARY WITH RESPECT TO THE EARTH which is rotating about an axis.

Similarly the earth is STATIONARY WITH RESPECT TO THE object which is also rotating with earth with the same angular speed.

All objects which are in motion with respect to earth are IN MOTION WITH RESPECT TO THE EARTH which is rotating about an axis.

Similarly the earth is IN MOTION WITH RESPECT TO the object which is moving relative to earth.

As long as its not touching the earth, or in its atmosphere, sure. Otherwise, it will be pushed along with everyhing else (or dragged, if you want to think about it that way). Even the gravitational attraction between the earth an outside object (in 'near' space) is enough to give is some momentum.

The surface of the Earth is not an intertial reference frame, because the Earth has several rotations. So implicitly the answer is "no".

no object on earth cannot remain stationary because if it remain stationary than we can feel earth is moving.
