There is an immense design and pattern in nature. Tides ebb and flow according to schedule. Spring, summer, autumn, and winter come back in unwavering succession. The planets never leave their courses, the same cause always produces the same effect.
The spiral shape of the minutest shell on the sea shore is echoed in the spiral formation in crystals, in the spiral arrangements of nebulae, the spiral in the seeds of plants, the horns of animals, the bones and muscles of the human body, the curving shape of birds feathers, the trunk and branches of a tree.
Purposeful design is to be found in every part of the natural world, organic and inorganic and in outer space.
