Alfred's hypothesis was that all the continents were a big land mass which he called Pangaea because if you see a world map it is like a jigsaw puzzle and other evidence is that some animal fossils were on other continents. Also the same rock range was found on different continents.
Alfred Wegner believed that continents moved because of earth's plates shifting. Because he could not prove why they moved because of the day in age he live, most scientist didn't believe him. Now, with the science we have today, scientists have proved that our continents shift about 2cm a year.
Because Alfred Wegener couldn't specify the mechanism responsible for the movement of the continents, the continental drift hypothesis was rejected. This theory is now accepted science.
