I ( or anyone else ) cannot give any valid reasons why evolution could be or is a fairytale but I can give reasons why evolution is NOT a fairytale:
Island genetics, the tendency of small, isolated genetic pools to produce unusual traits, has been observed in many circumstances,...
The Larus gulls form a ring species around the North Pole.
The Ensatina salamanders, which form a ring round the Central Valley in California.
The Greenish Warbler (Phylloscopus trochiloides), around the Himalayas.
the grass Anthoxanthum has been known to undergo parapatric speciation in such cases as mine contamination of an area.
there are also some much more DIRECTLY observed instances of speciation:
Rapid speciation of the Faeroe Island house mouse, which occurred in less than 250 years after man brought the creature to the island.
(Test for speciation in this case is based on morphology. It is unlikely that forced breeding experiments have been performed with the parent stock.)
Formation of five new species of cichlid fishes which formed since they were isolated less than 4000 years ago from the parent stock, Lake Nagubago.
(Test for speciation in this case is by morphology and lack of natural interbreeding. These fish have complex mating rituals and different coloration. While it might be possible that different species are inter-fertile, they cannot be convinced to mate.)

How Do We Know That Evolution Has Occurred?
The evidence for evolution has primarily come from four sources:
the fossil record of change in earlier species
the chemical and anatomical similarities of related life forms
the geographic distribution of related species
the recorded genetic changes in living organisms over many generations
-the link then explains each in detail.
