Evolutionists cannot come up with an explanation for the origin of flies. Yet, surprisingly, though they cannot explain the formation of a tiny fly, they attempt to explain the transformation of gigantic dinosaurs into birds. Moreover, they fabricate an imaginary scenario asserting that dinosaurs who flapped their front legs to hunt flies took flight. It is, undoubtedly, senseless for a theory which cannot come up with an explanation even for a tiny fly, to comment on how completely flightless creatures managed to take to the air.
Evolutionists have valid reasons for not mentioning the origin of flies. First of all, flies have a perfect flight mechanism, which cannot be wholly imitated even with today's technology. An average fly has a wing system that enables it to flutter its wings 500 times a second. Moreover, this system is planned so perfectly that it is able to move both its wings simultaneously at such an amazing speed. Apart from this, it has a complex respiratory system. It can use the oxygen it needs to fly in a much quicker and much more efficient way than other living things.
English biologist Robin Wootton describes the perfect creation of the fly as follows:
The better we understand the functioning of insect wings, the more subtle and beautiful their designs appear. . . . Structures are traditionally designed to deform as little as possible; mechanisms are designed to move component parts in predictable ways. Insect wings combine both in one, using components with a wide range of elastic properties, elegantly assembled to allow appropriate deformations in response to appropriate forces and to make the best possible use of air. They have few if any technological parallels - yet. (Robin J. Wootton, "The Mechanical Design of Insect Wings", Scientific American, v. 263, November 1990, p.120)
