The worldwide presence of fossils, including some at the poles, is generally good evidence for a global flood. Former living creatures encased in sedimentary and volcanic deposits on a global scale. In fact, the evidence is stark. It only remains foggy, or contradictory, to those who are inclined for personal reasons to reject the biblical texts. The only thing one can do is scoff in disbelief. The physical evidence remains fairly clear. Furthermore the account of the flood is by no means fantastic from either a literary or historic standpoint.
The antarctic continent wasn't always at the pole; it has drifted there over geological time. That drift is ongoing and measurable. The fossils on that continent are consistent with its theorised past position. Indeed it was a prediction of the theory of evolution that the antarctic continent would harbour marsupial fossils, and that prediction came true. I won't hold my breath waiting for any surprising prediction made by YEC to come true (hint:YEC is marked by an utter failure to predict anything that wasn't already known, ever).
The evidence is indeed stark. It falsifies biblical literalism at every turn. If the bible didn't exist there would not be a single shred of evidence that would lead anyone to conclude that the world is 6000 years old and endured a global deluge 4000 years ago. Geologists went looking for that evidence 200 years ago and concluded that it wasn't there. Nothing found since has changed that conclusion; on the contrary data from almost every field in science confirms the mainstream scientific position. I note you failed to address either of the specific points that I made (amongst many that I could have cited) that utterly refute any possibility of the geological record being explained by a global deluge.
