Because it is. There's no fundamental reason it has to be, though given the currently accepted model of how the Earth formed it would be extremely unlikely that the impacts of the many, many small bodies that made it up would be perfectly balanced.

An inclined axis is an axis that is tilted or sloped in relation to a reference point or plane. This tilt or slope can affect the movement or rotation of objects or systems that are interacting with the inclined axis.
The axis of the Earth is an imaginary line that runs from the North Pole to the South Pole, around which the Earth rotates. It is inclined at an angle of approximately 23.5 degrees relative to its orbit around the Sun, which is what causes the changing seasons.

23.5 degrees.
An Equinox occurs when neither end of the Earth's axis is tilted toward or away from the sun.
The imaginary line that goes from pole to pole through the interior of the Earth is called the Earth's axis. It is an imaginary line around which the Earth rotates, and it is inclined at an angle of approximately 23.5 degrees from the perpendicular to the plane of Earth's orbit around the Sun.
Axes aren't inclined, they are tilted. Orbital planes are inclined, and Jupiter's is inclined about 6 degrees from the Solar equator. Planes can also be inclined relative to the ecliptic or the invariable plane. Jupiter's axis is tilted about 3 degrees from the ecliptic.
An inclined axis refers to an axis that is tilted or slanted in relation to a reference plane. In the context of mechanics or physics, it often pertains to rotational motion or the orientation of a rotating object. The inclination of the axis affects the behavior and stability of the object in motion.

The inclination of the Earth's axis is important because it causes the change of seasons as the Earth orbits around the sun. This tilt is responsible for the variations in the amount of sunlight different parts of the Earth receive throughout the year, influencing temperature and weather patterns. It also plays a role in driving ocean currents and shaping climate patterns on a global scale.
