I invite you to actually read that article all the way to the end. The classical examples of ring species may be oversimplifications but the concept of gradual gene flow is still very much intact (obviously).

As for your first point: don’t just selectively ignore what I’ve written and linked to. Beyond that, there is ample evidence. And it’s not hard to find, I’d invite you to honestly try. But I’ll stop here since I don’t have much hope of actually convincing a creationist. I posted the information for the benefit of others.
