It’s hard to believe but a long time ago, the world as we know it might have been one huge continent
Even though there was some speculation about the movement of continents back in the 16th century, this theory was left rejected and underdeveloped for almost 4 centuries for lack of any motive mechanism. However, some scientists lingered on the idea for a while after it was rejected in 1596 but were unable to back it up with enough scientific evidence. That was until Alfred Wegener’s paper was published in 1912.
