We're not quite sure what the question means by "earth's tilt" or "stay the same".

The axis of the earth's rotation is inclined about 67.5 degrees to the plane of

the earth's orbit, and that doesn't change. Over the course of a human lifetime,

or several human lifetimes, the pole of earth's axis remains pointed toward the

same spot in the sky, presently quite close to the star Polaris. Over a period of

26,000 years, the pole describes a circle in the sky, but the axis remain inclined

to the plane of the orbit by the same 67.5 degrees.

So we must take issue with the premise of the question, and say that the earth's

"tilt" does in fact "stay the same".

Why does the cycle of seasons on earth always remain the same?

The cycle of seasons on Earth remains the same due to the tilt of Earth's axis as it orbits the sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons. This pattern repeats annually as Earth continues its orbit.


Why is earths tilt sideways to the sun andhours of daylight and darkness the same in both hemispheres on about March 20?

Earth's tilt causes different regions to receive different amounts of sunlight throughout the year. On March 20, the tilt is such that the hours of daylight and darkness are approximately equal in both hemispheres, marking the spring equinox. This occurs because the tilt aligns the equator with the center of the sun, resulting in equal distribution of sunlight.


Why does the constellation change possition in the night sky?

The constellations change position because of the same reason the days range in length from summer to winter. The Earth's tilt and wobble. The constellations stay in the same place in the sky, but every day the Earth moves while the tilt stays the same, leaving it to appear that the constellations have moved. (It's better to understand with a picture..)

Why does Mars have similar seasons to Earth's?

That's because Mars has an axial tilt which is almost the same as the Earth's. A planet's axial tilt is the most important factor in determining the seasons.
