Alfred Wegener noticed that the coast of South America seemed to fit into the coast of AFRICA, just like a jigsaw puzzle.

Alfred Wegener named his single land mass the Urkontinent or Pangaa. This has passed into general use as Pangaea.
A man named Alfred Wegener first presented the theory of plate tectonics, but had no proof, so other scientists laughed at him. later, Arthur Holmes decided that it wasn't such a laughing matter, due to the theory of convection currents in the mantle. so Alfred Wegener first presented it, but Arthur Holmes proved it. hope this helps.
Alfred Weqener's theory/ hypothesis was considered controversial because Alfred did not have an explanation for why the continents, North America, South America, Africa, Asia, Antarctica, Australia, and Europe have separated or moved.

Alfred Wegener's famous theory was that all of the continents joined together to form one large super-continent; Pangea.
Alfred's super-continent is call Pangaea meaning 'all lands' in Greek!
Alfred Wegener proposed it. He noticed similarities in fossils in places like Western Africa and Eastern South America. Then, he noted that those two continents could fit together, like puzzle pieces. He proposed that they used to be joined, and although his theory was not taken seriously at first, we now know he was correct.
i think he called it pangaea or pangea(i think)
