there is no way that earth could expand with no reason and expecially no reason why such theory would be required, because you will have harder time to explain that expansion mechanism and rewrite half of physic than just accepting some more practical solution.

Back after enforced absence
To get on with the business of answering points I want to put this idea that the continents bumping around can explain the coastline matches to rest.
Imagine if Pangea started on the other side of the Earth, and that Pacific spread resulted in the present approach of Europe/Africa towards the Americas. 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.
