Once again, the scripture states nothing about a "Temple".
It clearly states "Wall & Street", if God intended any more that pertained to the 70 week, 490 day prophecy it would be written in Daniel 9:24-27
Daniel 9:24-27KJV
24 Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.
25 Know therefore and understand, that from the going forth of
the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks:
the street shall be built again, and the wall, even in troublous times.
26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined.
27 And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
If you choose the believe that the 70 weeks prophecy pertains to 490 days and only encompasses rebuilding a street and wall then that’s on you. The prophecy itself reveals that Jerusalem was to be rebuilt which includes the city and sanctuary.
25 “Know therefore and understand,
That from the going forth of the command
To restore and build Jerusalem
Until Messiah the Prince,
There shall be seven weeks and sixty-two weeks;
The street shall be built again, and the wall,
Even in troublesome times.
The time frame of the first 69 weeks runs from the going forth of the command to restore and build Jerusalem until Messiah the Prince.
Cyrus was king of Persia in the year 539 BC.
By the time Messiah the Prince came about Rome was the World ruling empire.
So your theory of the prophecy spanning 490 days doesn’t make sense.
The person who commanded the work to begin plainly revealed that God told him, Cyrus, to build Him a house.
That is the purpose, God Himself raised up Cyrus to be king to do.
Thus says Cyrus king of Persia:
All the kingdoms of the earth the Lord God of heaven has given me. And He has commanded me to build Him a house at Jerusalem which is in Judah. Ezra 1:2
Again
28 Who says of Cyrus, ‘He is My shepherd,
And he shall perform all My pleasure,
Saying to Jerusalem, “You shall be built,”
And to the temple, “Your foundation shall be laid.” ’
Thus says the Lord to His anointed,
To Cyrus, whose right hand I have held—
To subdue nations before him
And loose the armor of kings,
To open before him the double doors,
So that the gates will not be shut:
2 ‘I will go before you
And make the crooked places straight;
I will break in pieces the gates of bronze
And cut the bars of iron.
3 I will give you the treasures of darkness
And hidden riches of secret places,
That you may know that I, the Lord,
Who call you by your name,
Am the God of Israel.
13 I have raised him up in righteousness,
And I will [d]direct all his ways;
He shall build My city
And let My exiles go free,
Not for price nor reward,”
Says the Lord of hosts.
Isaiah 44:28-45:3,13
Cyrus was anointed by God and raised up for the very purpose of releasing the children of Israel back to the land the Lord had given them and restore the city of Jerusalem which includes the Temple as well as restoring to them the provision to do this very thing.
In addition Cyrus returned to them the articles to be used in the Temple.
King Cyrus also brought out the articles of the house of the Lord, which Nebuchadnezzar had taken from Jerusalem and put in the [d]temple of his gods; 8 and Cyrus king of Persia brought them out by the hand of Mithredath the treasurer, and counted them out to Sheshbazzar the prince of Judah. 9 This is the number of them: thirty gold platters, one thousand silver platters, twenty-nine knives, 10 thirty gold basins, four hundred and ten silver basins of a similar kind, and one thousand other articles. 11 All the articles of gold and silver were five thousand four hundred. All these Sheshbazzar took with the captives who were brought from Babylon to Jerusalem.
Ezra 1:7-11
Why would the children of Israel need the articles of the Temple if they were not working on restoring the Temple?
