Humans are apes. Chimpanzees, orangutans, gorillas,... all apes. The ancestral animal that humans evolved from no longer exists as it was before it evolved into chimps and humans.
Many many species of animals no longer exist because they evolved. Species become extinct as they are no longer able to cope with changing circumstances.
Evolution is the answer to what happened to all the life forms that we see in fossils that do not exist today. For example, the dinosaurs appear to be the ancestors of birds. So, while the dinosaurs are extinct, they live on as the species into which they evolved.
You will not find the ape form that humans evolved from living today because it evolved. Any life form that does not adapt to changing circumstances is doomed to extinction.

Humans *are* apes, descended from earlier apes. Our closest relatives are chimpanzees, and the most recent common ancestor of both humans and chimpanzees was approximately 6 million years ago.
The way to understand our origins is to remember that living organisms are in a state of constant change - It's not that evolution *can* occur, but that it *must* occur, simply because there is no mechanism in living organisms to ensure perfect, flawless reproduction for ever.
Suppose you could study a population of chimpanzees in the jungle, on a timescale of millions of years. Clearly, each individual only lives a few decades, so the population is constantly being succeeded by individuals which are different from their parents, because reproduction is imperfect - and remember, this is *inevitable*. It can't *not* happen. All the time this population is inter-breeding, the genes are getting mixed together, and only genes which work well with all other chimpanzee genes will tend to get passed down to successive generations (because individuals with genes that don't work well together will tend not to survive and reproduce).
However, suppose that circumstances arise which cause a group to become genetically isolated from other chimpanzees. This could be as a result of an accident of geography (e.g. an impassable river) or breeding preference or simply great distance. There will develop two distinct groups of chimpanzees which can never again exchange genes, because they have become different enough that mating will not produce viable offspring. This is what biologists define as speciation - i.e. the population has forever split into two distinct groups. Biologists have observed many instances of speciation, so there is no doubt that it occurs.
Assuming that both groups continue to survive, it is again *inevitable* that they will diverge genetically - There is no possible way that both groups, isolated and independent from each other, can change in exactly the same ways, and the longer they continue to breed, the more different they will become. Over millions of years, given that the rate of genetic change via mutation tends to remain fairly constant, the two groups will become as distinct as today's chimpanzees and humans are from each other, and from their most recent common ancestor.
All this is based on what we *know* is true - it's not supposition or guesswork, and remember it's not just possible, it absolutely *has* to happen, because there is no mechanism in biology to make reproduction a 100% perfect, flawless process.
NB: The reason we're classed as apes is that there is no valid way to group all the other apes together that doesn't also apply to humans. In other words, whatever criteria you use to define what is an ape, in order to include chimpanzees, gorillas, orangs and gibbons, humans will also fit those criteria. Indeed, chimpanzees are more closely related to humans than to gorillas, and gorillas are more closely related to humans and chimpanzees than they are to orangs, so any classification that separated humans out from those other apes would not make any sense.

it was the other way around apes evolved from blondes, the lower form species

Darwin proved it and it is still scientifically discussed and analyzed, in fact we have evolved from some animal or the other, each animal evolution is somehow connected to some organism and you cannot evolve from absolute zero

If Christians came from Jews, why are there still Jews around?
P.S. We are apes right now, just like we are mammals.
