Flies appear suddenly in the fossil record with all their organs and functions fully formed, invalidating evolutionist claims. The fact revealed by the fossil record is that flies did not evolve gradually from some other species. From the moment they first came into being until the present day, they have not changed at all. The 45-million-year-old long-legged fly fossil pictured is one proof that these flies have never changed?in other words, that they never evolved.
