he was a prophet read the book of Haggai in the Bible if you don't believe me!
Haggai
The Book of Haggai is written by the biblical prophet Haggai. He was tasked with encouraging the Jewish people to rebuild the Temple in Jerusalem after their return from exile in Babylon.
Because the prophet Haggai told them, in the name of God, to do so.
Haggai was known as one of the minor prophets and served as such during the reign of Darius. Most of the prophecies of Haggai are concerned mainly with rebuilding the temples after the Babylonian Captivity.
Some say the object of the Book of Haggai seems to be to immortalise Haggai by giving him credit for commencement of the Temple, suggesting that the book was written much later when there were no longer any witnesses to refute the claim. On that view, Haggai could not have been the real author. We simply do not know.

No, Haggai was a man. He was a prophet in the Hebrew Bible who lived during the time of the Babylonian exile and encouraged the people to rebuild the temple in Jerusalem.
Haggai is a prophet in the Old Testament who is known for encouraging the Jews to rebuild the Second Temple in Jerusalem.
Zechariah was a contemporary of Haggai, Ezra, and Nehemiah. They were all involved in the restoration of the temple and the rebuilding of Jerusalem after the Babylonian exile.
Daniel was alive at the time; and probably also Haggai, Zechariah and Malachi.
Haggai and Zechariah were prophets at the time of Ezra and Nehemiah. Ezra 5:1 Now Haggai the prophet and Zechariah the prophet, a descendant of Iddo, prophesied to the Jews in Judah and Jerusalem in the name of the God of Israel, who was over them.
