Believing in evolution with the exception of human evolution is like believing in the internal combustion engine with the exception of the Chevy V8.
You seem to be profoundly unaware of how science works.
Since people made up various religious texts, others have been produced denying the veracity of those that proceeded them. However, none of them can prove themselves to be true or others to be untrue.
Scientific theories arise because of a burden of evidence supporting them. Sometimes new evidence causes refinement, revision. Please note I use 'theory' in the sense of 'gravity', not 'string'; the later is more if a hypothesis.
When new evidence appears, it can take a while and oft times some argument - not always dignified - until there is a consensus of what it means and how it impacts the understanding of whatever field of science it falls under.
I could go into detail about the decade-long bitchfest that is the 'out of Africa' and 'multi-regionalism' debate about our origins. For a long time the Afria lobby held the winning cards, but now new genetic methods are finding traces of H. neanderthalis and H. denisovius (sp?) ancestry in H. sap (us) X chromosomes, which kind of hints H. erectus evolved into the above regionalised humans before a further wave of H. erectus descendants (in this case H. sapiens) rolled out of Africa and displaced them with some admixture.
H. florensis is a sideshow, albeit an interesting one.
It in no way, shape or form puts into doubt that around 5 million years ago there were primates who were the ancestors of us AND chimpanzees.
There is proof of this in our bones, in our genes, and in the ground (i.e. fossils).
Feel free to question things though; however, given your level of education about evolution and you desire to believe in things not supported by evidence, you will be liable to error and rushing off to conclusions that fit your prexisting desire to not believe in human evolution.
If you really wanted, you could study the subject.
Anyway, I didn't make the thread to start an argument, truly. I only wanted to show that even "science" doesn't always agree... or know. Even when they say they do.
