I've seen your picture, you are correct Orangutans, spitting image

Obviously, humans evolved originally from bacteria roughly 4 billion years ago. We continued to evolve and evolve and evolve and evolve.

About 63 million years ago primates split into two groups, "known as the haplorrhines (dry-nosed primates) and the strepsirrhines (wet-nosed primates). The strepsirrhines eventually become the modern lemurs and aye-ayes, while the haplorrhines developed into monkeys and apes – and humans.

So we also evolved from stresirrhines.

About 25 million years ago apes split from the old world monkeys. We know from DNA evidence that humans are apes so therefore it is very obvious that these first apes are our recent ancestors--not as old as our oldest ancestors which are 4 BILLION years old.

18 million years ago Gibbons split off from the other apes. Humans did not come from the gibbons line. Human dna was still moving through the lineage of the other apes who had not yet diverged. (Humans will not diverge from these other apes for a while yet)!

14 million years ago orangutans branch off from the other great apes, spreading while their cousins remain in Africa. Human dna is still travelling along the line of the other apes.

7 million years ago...WHOOPS...gorillas are branching off! (But humans are still plowing along with the other apes)!!

6 million years ago the human ape diverged from the chimpanzee ape and the bonobos!

So apes existed for about 19 million years before "human" apes did! Humans are apes and they evolved from older apes. Humans are very very YOUNG apes!

Recently the homo sapiens ape evolved from the homo erectus ape!

Of course, we evolved from the very first ape and the very first primate and the very first mammal and so on and so forth elsewise we could not have arrived here other than through spontaneous generation!

This little movie chart shows when chimpanzee apes and human apes diverged from other apes but remained in the TREE of apes. Humans are now a BRANCH coming off of the tree of apes. Actually, the original tree is a bacteria tree. They are the oldest ancestors from whom we evolved!

Before leaving this topic (and to be entirely fair) I must mention that there are a couple of competing theories of human evolution. Some people believe that the human ape branch does not connect to a tree but floats in some sort of ether held up by invisible strands of spaghetti. Others believe that we spontaneously sprang from rocks about 4 billion years ago with our bodies already full of bacteria. Still another theory is that we did not diverge from the tree of apes but spontaneously sprang into existence about 6 million years ago out of a hollow tree. Proponents of this theory believe that the bacteria and the ape DNA were "just there" and that some things cannot be explained.

One last criticism of the mammal-primate-monkey-ape explanation is embedded in the question. If we evolved from bacteria then why are there still bacteria?? This is similar to the question: If chimpanzee apes evolved from other apes then why are there still humans? The usual answer given is that it is not necessary that humans and all other apes go extinct when any particular ape classification speciates. I know you do not find this puzzling but some people apparently do and I see no easy way to alleviate their distress--but there you go...
