Exactly!

While the continents might look like they fit together, and the rock types and ages and fossils match at key points all down the coasts from Canada/Scotland all the way down to South America and South Africa, how on earth (sorry) would you explain how the continents are thousands of miles apart?

One theory posited the earth spinning so fast centrifugal forces ripped ehat would become the moon out of the Pacific, sucking Eurasia and America into the void.

That's a Randall Monroe WhatIf if ever I saw one. Think of the energy involved! All life on earth would be extinct.

So these theories were laughed out of scientific court. Until Vine and Matthew's seminal paper on magnetic stripes being mirrored over the mid ocean ridge showed there had to be something forcing the plates apart.
