Throughout the ages, humanity’s spiritual, intellectual and moral capacities have been cultivated by the Founders of the great religions, among them Abraham, Krishna, Zoroaster, Moses, Buddha, Jesus Christ, Muhammad, and—in more recent times—
the Báb and
Bahá’u’lláh.
These Figures are not simply ordinary people with a greater knowledge than others. Rather they are
Manifestations of God,

The holy Manifestations Who have been the Sources or Founders of the various religious systems were united and agreed in purpose and teaching. Abraham, Moses, Zoroaster, Buddha, Jesus, Muhammad, the Báb and Bahá’u’lláh are one in spirit and reality

"It can, therefore, be confidently stated that the teachings of the Faith name Krishna as a Manifestation of God. In light, however, of the other statements of the Guardian, in which he stresses the paucity of our information about the beginnings of Hinduism, we should be cautious not to assert the historical accuracy of specific stories related about Krishna. A similar case where allegorical statements and legends surround the figure of a known Manifestation of God is that of Adam." On behalf of the Universal House of Justice...
"The Adamic Cycle inaugurated 6000 years ago by the Manifestation of God called Adam is only one of the many bygone cycles. Bahá’u’lláh, as you say, is the culmination of the Adamic Cycle.

Here's one that
says Noah was a manifestation but in the quote it says "prophet"...
Noah was a Manifestation of God. "...consider that among the Prophets was Noah. When He was invested with the robe of Prophethood, and was moved by the Spirit of God to arise and proclaim His Cause, whoever believed in Him and acknowledged His Faith, was endowed with the grace of a new life." ( Bahá'u'lláh, Kitáb-i-Íqán, par. 162)
But I don't believe Adam, Noah, Abraham or Moses were manifestations. Actually, probably none of the people listed accept Baha'u'llah. And with him, what I really believe is that he claimed to be a manifestation, but because he said some of these other people were too, I don't believe him.
