Now, despite the match of coastlines, we must argue that they approach and match by co-incidence, or because they had been previously joined in some previous migration.

The standard Earth model argues in the same way for the matching of Pacific coastlines.

Now as we accept that Stars grow and contract without invoking aliens and big lasers why not consider some nuclear mechanism that does the same for planets? After all, the evidence for expansion is compelling.
