What is the primary body that influences Earth's ocean tides?

The primary body that influences Earth's ocean tides is the Moon. Its gravitational pull creates bulges in the Earth's oceans, leading to high tides in the areas directly beneath and adjacent to it. The Sun also plays a role in tidal changes, but its influence is less significant compared to that of the Moon. Together, these celestial bodies create the complex patterns of tidal movements observed on Earth.
