We are a ball of rock spinning around the sun in a galaxy that is also rotating and moving through space. How is it that we still see the same constellations as seafarers thousands of years ago considering all of this movement?

well, stars are incredibly far away. So we need to cover a lot of distance until we notice a relevant change.
If you drive with your car at night and look at the moon, it seems like it is standing still. Same principle.
Also, constellations DO change. For example, right now we can still refer to polaris as the star which is roughly aligned with the axis of earth. But this won’t be the case forever. Some day in the future, there will be another star we’ll use as reference.
