Velvethammer makes a good point, and I would like to know why also. I know theirs been a few changes, but not soo much like from Monkeys to Humans in that time frame.(I think Monkeys to Humans or some animal similar to them)
Again not claiming which side is better or not, just curious.
What you are missing is the concept of speciation. Different species form when one population gets isolated from the other. One of the populations then moves off in a different direction for different reasons such as moving into a different niche and environment.
Lets us use a possible example assuming Ardipithecus was the last common ancestor with Chimps and humans and assume everything I say is just a hypothetical example. This creature was an upright animal that had a chimp sized brain and lived both on the land and in the trees. They were successful and their range expanded across a thousand square miles. A population got across and river at one point but the river was too big to allow for anyother migration across.
One group started becoming more elvolved for the trees and they developed into Chimps. They developed knucklewalking as their arms grew stronger and to aid in moving through the undergrowth. Since they didn't need to develop language, their brains remained relatively the same. They were still quite intelligent.
The other group further developed its bipedalism. It then became a hunter and developed a physical means to chase down prey with highly evolved sweat glands. They developed sophisticated language and culture and their brains grew large.
This is just a glimpse how chimps and humans may have evolved. In this example, we both evolved from the ape Ardipithecus which is possible. It may be that our common ancestor was something before Ardipithecus but it doesn't change how they might speciate.
We didn't evovle from chimps anymore than chimps evovled from us. We both evolved from common ancestors. With dogs, we know from genetics that they all descended from grey wolves yet they evolved into so many different forms. They are still technically the same species but even domestic dogs would speciate if their populations were isolated long enough from each other.

There was no original man and woman? O really? where did mom and dad's mom and dad's mom and dad originate from?
Actually there was no original man or woman, there was never a point during evolution where you could say "aha! that's the first man and woman". Every animal has belonged to the same species as its parents.
Evolution is too slow a process to make definitive statements such as 'the first man and woman". It's like taking a photo of a baby through to old age every day, in each photo the person looks exactly the same as the photo of the day before, you could never at one individual photo point at the transition of baby to child, child to teenager, teenager to man etc.
