EARTH'S TILT AND ROTATION

The earth's axis of rotation is tilted 231/2 degrees relative to the perpendicular of the earth's plane of orbit. This tilt causes the four seasons. During the months of May, June, and July the northern hemisphere is pointed toward the sun, causing the hemisphere to warm and bringing on the season called summer. During November, December, and January the northern hemisphere is pointed away from the sun providing colder temperatures and the season called winter. Why is this tilt 231/2 degrees? Why not some other value?

What if the earth had no tilt, and the axis of rotation remained perpendicular to the plane of orbit? We would have no seasons and the surface temperature at any point on the earth would be the same during both July and January. The equatorial region of our planet would be intolerably hot all year and the poles would remain fairly cold. Ice would accumulate at the poles. The weather patterns would be stationary with permanently positioned warm and cold air masses. Some areas would continually be very humid while other areas would be quite arid. Only the mid-latitudes would be comfortable for human habitation and suitable for cultivation. Only about one half of our presently farmable lands could grow crops.

What would be the effect if the earth had double the present tilt? Temperature extremes between seasons would be much more pronounced. Even the mid-latitudes would have unbearable heat in the summer and frigid cold in the winter. Most of Europe and North America would experience very prolonged darkness in the winter and very prolonged daylight in the summer. Life on most of the earth's surface would become intolerable.

If the earth did not have this exact tilt, then life would be very bad for us all. So, why is this happening? Please explain?
