Did humans really evolve from modern apes like orangutangs and gorillas or chimpanzees?

No we evolved from great apes not modern apes. Modern apes also evolved from great apes. Great apes have long been extincted

No, evolution theory is racist, say no to racism, we are all the same.

No, MODERN APES and humans evolved from a common ape ancestor from millions of years ago..

True. The chimpanzee–human last common ancestor (CHLCA), also known as Pan Prior, is the last common ancestor shared by the extant **** (human) and Pan (chimpanzee and bonobo) genera of Hominini. Due to complex hybrid speciation, it is not possible to give a precise estimate on the age of this ancestral population. While "original divergence" between populations may have occurred as early as 13 million years ago (Miocene), hybridization may have been ongoing until as recently as 4 million years ago (Pliocene).

The closest living relative of Humans is the chimp, and the next closest is the gorilla, with the orangutan next. These 3 apes are quite similar but they do have their differences. For example, the orang has orange fur, not black fur, and the orang does not walk on its knuckles, while the chimp and gorilla both do.
It is therefore most likely that the ancestor of humans walked on their knuckles. As to how similar they are to chimps or gorillas, we really have no idea. That is because we last shared an ancestor with chimps about 5 million years ago, and 5 million year old chimp fossils have never been found. Gorilla fossils that old are not know either, because fossils do not preserve very well in forest environments, where apes live. Therefore we do not know if we looked more like the chimp or the gorilla unless and until fossil apes that old are found. There are numerous possibilities. The gorilla and/or the chimp may be living fossils and they have not changed at all for 5 million years. Or the chimp probably has changed more than the gorilla since that time. The chimp may have evolved from a gorilla since they are so small that they do not need to walk on their knuckles, but they knuckle walk anyway. Without fossils, we can make educated guesses by comparing their current forms and figure out their similarities and differences.
What we do have are fossils that are intermediate between apes and humans. They are called australopithecines, and they in general have skulls that look like apes, albeit slightly larger braincases than apes for a slightly bigger brain, and they also walked on 2 legs. They range in age from about 4.5 million years old to about 1.8 million years old. These fossils, which have features found in both apes and humans, are strong evidence that our ancestor was an ape. What we do not know is whether our ape ancestor looked more like the gorilla, or the chimp or even the orangutan with the exception of walking on their knuckles. My guess is that our ape ancestor was intermediate in size and built between the chimp and the gorilla, i.e. bigger than a chimp but smaller than a gorilla. All African apes (including our ancestor) probably resembled the gorilla the most. As African forests started to shrink because of increasing aridity, some of the apes were driven out of the forests. Our ancestor were forced to live in the savanna, and we evolved to be hairless and bipeds. The chimp's ancestor were unable to maintain a home in the best forest habitats because they lost territorial battles with stronger apes, so they settled in less productive forests. Because there is less food in their habitat, they have to start hunting for monkeys and other sources of meat, and they evolved to be smaller to allow them to climb trees in pursuit of monkeys. Adult gorillas rarely climb tree, because it is dangerous if they fall from a tree. The gorilla too may have evolved to be even larger than they were because only big ones can win a habitat within the best forest habitats.

The *other* modern apes (humans are also part of the Great Apes) are just as evolved as humans, and just as far removed from our common ancestor.
Chimps, Bonobos, Orangutans and Gorillas are analogous to our cousins, not our parents or grandparents.
@Gray Bold - That last common ancestor with modern chimps was NOT a modern chimp. It was an ancestor to modern chimps, just like it was an ancestor to modern humans.
