Question: Have there been any publications or studies to prove my novice theory that the moon formation had something to do with the origin of the continents? I was able to find a couple references from Harvard papers, but honestly and obviously it would take a degree to decipher 90 percent of it. In which case I would be answering my own question. Even here the closest answer is that they formed in the early Hadean.

So is this an accepted theory I just haven't ran across, or has it been considered much before?

Repeating this process over billions of years worth of magmatism is what is generally accepted to have led to the gradual (and more or less permanent) growth of the continents.
