The following is my own my making.
1. I called the archaeologist most knowledgeable about the ancient Egypt in the state to ask.... .

I'd like to know when the superlative modifies it behind a noun, if "the" is positioned before the noun"
Thank you in advance for your help.

Your question isn't clear, but "the archaeologist most knowledgeable" means the same as "the archaeologist who is [the] most knowledgeable" (the second definite article is optional).

There is one mistake: we would say "ancient Egypt," not "the ancient Egypt."

Did you write this sentence fragment yourself, park sang joon, or is it from the source you cite?

I wrote it for myself.

I thought I tell one of every Egypt in time period.

 

[Florentia52]

There's only one Egypt, even if it has gone through many time periods.

Thank you, Florentia 52, for your additional information.
Then, I was wondering why we use "the spoken English," not "spoken English."

We would ordinarily say "spoken English" not "the spoken English." Perhaps there are exceptions - and perhaps there are with "ancient Egypt" too - but under nearly all normal circumstances, we would not precede either of these with an article so long as they're functioning as nouns. Thanks to Google, I see that there is some sort of program called The Spoken English Program, but that's not what I'd consider a "normal circumstance."

That's not the spoken English - it's the program, with Spoken English inserted adjectivally as the title.
