And you're entitled to that opinion. Fortunately though you are not the leading authority on that issue - the United States government is and the United States government officially recognizes St. Eustasius as its first diplomatic exchange and has formally states so in multiple State Department documents and at least two presidential proclamations (FDR and Bush Sr.) in the last century.
Neither could be considered a recoginized nation for the first three years of existance.
Then I'll ask you again - when do you date the beginning of American nationhood to if not July 4, 1776?
Ofcourse it does, because it was!
That doesn't mean that the diplomatic recognition of St. Eustasis meant anything to the rest of the world, which is what getting recognized as a nation is all about.
We honor St. Eustasius for being the first to recognize us, but that had nothing to do with worldwide recognition.

That is when we recognize our nationhood, but had we not survived (like the Confederacy didn't) there would be no date to celebrate.
When is the Confederacy date of independence anyway?
