The earth’s tilt makes its axis point to the direction of the North Star, Polaris, in the northern hemisphere. The ancient mariners and seafarers used the stars in the sky as signposts for navigation. But more importantly, the earth’s tilt has made possible the seasonal variations in the regime of day length, intensity of solar rays, and rainfall supply as the earth completes its annual orbit. For example, in the northern hemisphere, the short day periods and long winter season during the winter solstice are gradually replaced and compensated by the longer days and intense sunlight of the summer solstice. Thus, in the corn growing areas in Iowa, USA, day length extends beyond 16 hours during the cropping season and record yields of 26 t/ha of corn are obtainable due to high and extended photosynthetic activity, coupled with the application of modern technology. This yield level is not possible in the tropics where day lengths are shorter.

If the earth’s tilt were at a lesser extent (less than 10o) as with most planets, the northern and southern latitudes would not receive adequate amounts of sunlight. Winter would be longer and summer periods shorter. These conditions would be unfavorable for agriculture. Humanity’s supply of food would rely solely on the equatorial and tropical regions.

Thus, the earth is extremely favored by circumstances of: (1) being in an ideal position from the sun that makes life possible, and (2) having a celestial mechanism that ensures the equitable distribution of life-giving solar radiation throughout the latitudinal zones. This must be a part of the Intelligent Design.

Humans have long been enthralled by the beauty of the blossoms of springtime, the colorful hues of foliage in the fall, and the winter wonderland. Humans have been captivated by the grandeur of a full moon rising over the horizon. Antonio Vivaldi (1678-1741), the Italian violin virtuoso and great composer of instrumental music, dedicated four of his concertos to the “The Four Seasons.” They are the sentimental favorites during party celebrations and receptions. But the moon and the four seasons are not only a thing of beauty but also the giver of life for all humanity.
