The observation that stars appear to be in the same place over time is due to the vast distances between celestial objects and the relatively slow speed at which they move relative to us. While it is true that the universe is expanding on a large scale and galaxies are moving away from each other, the effect of this expansion is generally not noticeable on smaller scales, such as within our own galaxy.
Stars in our Milky Way galaxy, including our Sun, are gravitationally bound to the galaxy and follow its overall rotation and motion. The distances between stars within a galaxy are typically much smaller than the distances between galaxies, so the gravitational forces dominate and keep stars relatively close to their original positions over human timescales.
Moreover, the apparent motion of stars in the sky is mainly due to the Earth's own rotation and orbit around the Sun. As we observe the stars from our moving vantage point on Earth, they appear to rise and set, giving the impression of daily motion. However, the individual stars themselves are generally not moving significantly in relation to each other.
It's important to note that there are exceptions to this general rule. Some stars do have measurable proper motion, which means they have small but observable motions relative to distant background stars over long periods of time. Additionally, the positions of stars can change over extremely long timescales due to various factors such as gravitational interactions, stellar evolution, and the motion of the Milky Way itself.
In summary, while the universe as a whole is expanding and galaxies are moving apart, the stars within our galaxy appear to be in the same place due to their gravitational interactions and the vast distances involved. The apparent motion of stars in the sky is primarily caused by the Earth's rotation and orbit.
