While these questions all seemed very fresh and unanswerable upon their first arrival
When first presented, these questions seemed novel and without solution.
I was comforted to learn that there were no objections on my list that had not been raised even more forcefully and articulately by others down through the centuries.
My list had objections.
These objections (of mine) were forceful and articulate.
Others down through the centuries (from the past) have raised objections that are of greater force and more articulate than mine. The arguments from the others are (even) more forceful and articulate than mine.
In fact, all of my objections have been covered by others before; therefore, none of my objections are not covered.
