The most convincing evidence I have found for the expanding Earth theory is provided by reconstructing all the Earth's ancient crust like a gigantic jigsaw puzzle.

The continents are ancient and have certainly existed for more than 200 million years. In geological time scales the Ocean Floor is relatively young and ranges from over 200 million years old to some which is still forming today. The youngest of this ocean floor can be gradually removed to allow the remaining Ocean Floor to be joined together, but these areas can only be completely joined if the size of the Earth is reduced. The rotating globe above has had all the Ocean Floor created in the last 50 million years removed and the size of the Earth has been reduced slightly to allow the remaining Ocean Floor to join together again.

Consider how unlikely it is that all the ocean floor fits together so precisely to form a complete sphere. If the missing 50 million years of Ocean Floor had been generated by any other process than an expanding Earth it would be improbable that the areas were the exact shapes required to reconstruct a smaller Earth. Surely it would be more likely that irregular shapes would have been left. It would be similar to arguing that a jigsaw puzzle fits together by chance. It would be even more remarkable if this process could be continued further into the past but this is exactly what happens.
