I rarely post here, but the OP has shown such a complete lack of understanding of the theory of (human) evolution that I feel inclined to point out a few niceties....
The "stright-line" theory of human evolution, where 1 species evolved directly into another, which then died out and evolved directly into another, is, indeed, a fairy tale. We have known for years that multiple species of the homo genus have existed within the same time period. There are some areas in Africa where fossils of multiple species have been found around lakes and so forth.
This does not disprove the case for human evolution from primates; it actually strengthens it. A common ancestor to modern homo sapiens would not have evolved only and directly into, say, homo habilis; there are many other branches that, at the time, may have possessed traits that gave these other species some kind of advantage in its specialized climate or environment. As an example, even a very introductory course to human evolution should explain that homo was not the only genus descended from Australopithecus; there was also the Paranthropus genus, which included P. Robustus. Does this disprove human evolution, or evolution in general? Absolutely not. P. Robustus had enormous, powerful jawbones and jaw muscles, which would give it a rather obvious advantage in an environment where its diet consisted of many kinds of seeds/nuts that needed to be cracked open. However, P. Robustus had a much smaller brain than other species, which would eventually be a distinct disadvantage.
Another example: according to 'straight-line' evolution, we would have descended from the neanderthals, but this is quite clearly incorrect, given the numerous anatomical differences between homo sapiens and homo neanderthalensis (the large bulge at the back of the head, the large brow ridge, the larger brain case (largest of all homonid species)), which make it clear that instead of evolving directly from neanderthals, homo sapiens have a common ancestor with them (likely homo antecessor or heidelbergnsies). Neanderthals and homo sapiens both existed in Europe at the same time period, but this quite obviously does not disprove evolution. The Neanderthal had a shorter stature than homo sapiens and could therefore survive better in colder climates, ie, especially during an ice age. Homo sapiens, on the other hand, are taller and better suited to 'modern' temperatures.
