These flies, belonging to the order Diptera, resemble very large mosquitoes. Their distinguishing features are the length of their legs and bodies. Some 14,000 species have been described to date, representing one of the most numerous families in the order Diptera. The countless fly fossils discovered to date show that these insects have always existed as flies, they are not descended from any other life form, and never underwent any intermediate stages. In other words, they demolish evolutionist claims, showing us that they are the work of Omniscient and Almighty God.
