When it comes to fossils, you cannot prove scientifically that any fossil is a transition from one specie to another. You cannot prove that this fossil gave birth to another fossil. You can't even prove that any specific fossil reproduced at all.
Again, no one is claiming that fossil A is creature B's ancestor. Generally it isn't even claimed that fossil species B is a transition from species A to species C.
What actually happens is that there's a hypothesis that, for example, tetrapods are the descendants of fish based on certain similarties between the 2 groups. A claim like that
demands that there were creatures transitional between the 2 forms. So science predicts the type of creatures that should have existed in the past, along with certain bodily features they would almost certainly need to have in order to make a living as a "transitional" creature. Science can also make a pretty good estimate as to the timeframe that such creatures should have existed. When someone then goes and digs in ground known to be of the correct age, and finds a creature that very closely matches a proposed transition, then that's very good evidence that your original hypothesis (tetrapods descended from fish) is worthy of further investigation. Not proof,
evidence.

Link. A potato and a rock look a like so do they have a common ancestor? I guess if you believe life originated in a primordial soup, then they do have a common ancestor.
A potato and a rock are only similar at an extraordinarily superficial level. Show me a rock made of carbohydrates with a known mechanism for heredity and we'll talk.
That link you provided wasn't of 2 unrelated species; it was of 2 species of worm that are very closely related but are genetically different enough to merit being classed as separate species. This does highlight very nicely how the word "species" in biology is as tricky to pin down and arbitrary as the word "planet" in astronomy. Fortunately nature doesn't care too much for semantics.
You could do with reading some proper research on evolutionary theory so you could start making some proper arguments, instead of these ludicrous strawmen based on a few hours of Kent Hovind video tapes.
