We don’t yet know with any certainty exactly where the split occurred, the oldest hominid, upright-walking(and thus in the same line or sidebranch of the line that led to modern humans)is Orrorin Tugenensis
So, no evidence exists of the common ancestor between chimps and humans.
“And what is the lineage between that ancestor and humans?”
Again, we don’t yet know with any certainty
Out of all the species studied for evolution, you would think human evolution would be most studied area. However, we still do not know the lineage prior to humans.
“And how did the genetic swapping occur between the chimp line and humans?”
Like horses and Donkeys used to be able to do. They can no longer produce non-sterile offspring, but that is a recent development. The process of two species splitting would happen over time, not overnight.
What evidence do you have to show that chimps and humans can produce/have produced fertile offsprings?
It is either fact or everything is illusion meant to fool us.
False dichotomy. It is not either human evolution is true or everything is an illusion to fool us.

Our knowledge of the fossil record is always being added to and I don’t keep up that well, but the evidence is there. Accept it or don’t but don’t falsely claim there is no evidence.
I’ll correct my statement, there is no direct evidence of the common ancestor between chimps and humans.
As for your claim that the similarity between chimps and humans is evidence for human evolution, then I claim that they are similar because they were designed by a common designer and is evidence of special creation.
Also, thinking about it, what is the common ancestor of gorillas, chimp, and humans? And what is the common ancestor above that with orangutans? And so on. Has any of these ancestors been identified?
Of course human lineage is intensly studied and we know a great deal about the primates that came before us.
And were any of these primates a forefather of humans?
We even know that there was genetic mixing between us and Neandertals, our closest cousins who died out ~25,000 years ago.
How exactly do Neandertals demonstrate that humans evolved?

You stated “Like horses and Donkeys used to be able to do.” So what do you claim?
Yes, it certainly is, because the evidence is clear, evolution is a fact, it has occurred throughout the history of life on Earth.
Then human evolution should be easy to demonstrate since it’s a fact.
