If the plane of the Earth's equator were not tilted with respect to the ecliptic plane, the daylight period would indeed be the same year-round, there would be no seasonal changes, and Earth's poles would not experience six-month-long nights. The tilt of the Earth's axis is responsible for the variation in daylight hours, the change of seasons, and the extreme daylight conditions at the poles. Without this tilt, these phenomena would not occur.
