You either believe, based on philisophical considerations, that your family tree goes all the way back to the apes and beyond (that would be your worldview)...
Well, yes, I guess you can believe this on philosophical grounds. I don't know of any like this myself, but I can't rule out their existence either.

...or you believe based on what we can actually see happening (the evidence) that humans give rise to humans and that your family starts and ends with humans
Actually, our belief that life evolved from a common ancestor over the past three and a half billion years is based on what we can actually see.
We can discuss the evidence if you want, although that would be more appropriate for another thread.

But you keep getting on a tangent off what I was responding to. Any theory about the origins of life is going to be based on a different data set (as yet incomplete) than the data set that shows the history of life after that origin (which is pretty conclusive). That is why we have a fairly good understanding (although not yet 100% complete) if how life has evolved, but we are still trying to understand how life originated.
But this is the difference between science and faith. We have some good ideas about how life evolved, but this is not faith. This view has been shaped for over 150 years by the accumulation and study of actual evidence -- the opposite of faith. This is why we do not yet have a clear and detailed theory about the origin of life -- because we do not yet have the necessary data, which science (but not faith) requires.
All that we know, like evolution, is based on evidence. Our admission of things that we do not yet know, like abiogenesis, is based on a lack of evidence.
This is different than faith, which makes stuff up and holds onto the made up beliefs in spite of the lack of evidence, and sometimes in spite of contrary evidence.
