The Urantia Papers (its original title), aka
The Urantia Book (1955, Chicago, US, original language: English): it being the self-proclaimed fifth (of five, so far) epochal, divine revelation to us humanity, authored by invisible, celestial, beings; Urantia being the name of our world, which meaning is found immediately at the front page of this

but please hold on, before you dismiss the
Urantia Revelation (because you may even decide, at some point, to peruse the whole book, of almost 2100 pages long and divided into four parts),
URANTIA has a thoroughly historically documented story of its own origins, and not only online, there are actual physical documents related to this.
URANTIA's very first paragraph, from its first Foreword paper (of 197 papers in total):
Paper:section.paragraph (page.paragraph)
0:0.1 (1.1) IN THE MINDS of the mortals of Urantia—that being the name of your world—there exists great confusion respecting the meaning of such terms as God, divinity, and deity. Human beings are still more confused and uncertain about the relationships of the divine personalities designated by these numerous appellations. Because of this conceptual poverty associated with so much ideational confusion, I have been directed to formulate this introductory statement in explanation of the meanings which should be attached to certain word symbols as they may be hereinafter used in those papers which the Orvonton corps of truth revealers have been authorized to translate into the English language of Urantia.
however, there are several more passages within
URANTIA speaking of itself and of the celestial beings themselves who authored it, too; and here's one of the most important ones without doubt (
emphasis in the original
URANTIA text):
92:4.4 (1007.4) There have been many events of religious revelation but only five of epochal significance. These were as follows:
92:4.5 (1007.5) 1. The Dalamatian teachings. The true concept of the First Source and Center was first promulgated on Urantia by the one hundred corporeal members of Prince Caligastia’s staff. This expanding revelation of Deity went on for more than three hundred thousand years until it was suddenly terminated by the planetary secession and the disruption of the teaching regime. Except for the work of Van, the influence of the Dalamatian revelation was practically lost to the whole world. Even the Nodites had forgotten this truth by the time of Adam’s arrival. Of all who received the teachings of the one hundred, the red men held them longest, but the idea of the Great Spirit was but a hazy concept in Amerindian religion when contact with Christianity greatly clarified and strengthened it.
92:4.6 (1007.6) 2. The Edenic teachings. Adam and Eve again portrayed the concept of the Father of all to the evolutionary peoples. The disruption of the first Eden halted the course of the Adamic revelation before it had ever fully started. But the aborted teachings of Adam were carried on by the Sethite priests, and some of these truths have never been entirely lost to the world. The entire trend of Levantine religious evolution was modified by the teachings of the Sethites. But by 2500 b.c. mankind had largely lost sight of the revelation sponsored in the days of Eden.
92:4.7 (1007.7) 3. Melchizedek of Salem. This emergency Son of Nebadon inaugurated the third revelation of truth on Urantia. The cardinal precepts of his teachings were trust and faith. He taught trust in the omnipotent beneficence of God and proclaimed that faith was the act by which men earned God’s favor. His teachings gradually commingled with the beliefs and practices of various evolutionary religions and finally developed into those theologic systems present on Urantia at the opening of the first millennium after Christ.
92:4.8 (1008.1) 4. Jesus of Nazareth. Christ Michael presented for the fourth time to Urantia the concept of God as the Universal Father, and this teaching has generally persisted ever since. The essence of his teaching was love and service, the loving worship which a creature son voluntarily gives in recognition of, and response to, the loving ministry of God his Father; the freewill service which such creature sons bestow upon their brethren in the joyous realization that in this service they are likewise serving God the Father.
92:4.9 (1008.2) 5. The Urantia Papers. The papers, of which this is one, constitute the most recent presentation of truth to the mortals of Urantia. These papers differ from all previous revelations, for they are not the work of a single universe personality but a composite presentation by many beings. But no revelation short of the attainment of the Universal Father can ever be complete. All other celestial ministrations are no more than partial, transient, and practically adapted to local conditions in time and space. While such admissions as this may possibly detract from the immediate force and authority of all revelations, the time has arrived on Urantia when it is advisable to make such frank statements, even at the risk of weakening the future influence and authority of this, the most recent of the revelations of truth to the mortal races of Urantia.
URANTIA was and is meant for all of course, so its text is online for free reading and downloading; and it's also in the public domain of its English text since the decade of the 2000's.
URANTIA validates the Intelligent Design theory, although of course it is not its main focus or revelation (encompassing countless revelations!), but yes it says many places within it that the universe was created by
GOD our Paradise Universal Father and there being a one and only Paradise Trinity, all and every person being One, etc, and yes GOD being ONE and the First Cause and Center Personality, and the uncaused CAUSE of ALL.
speaking of the intelligent design discovered in general, by the midwayers or midway creatures, resident in our planet (midway between we humans and the angels):
58:2.3 (665.6) And yet some of the less imaginative of your mortal mechanists insist on viewing material creation and human evolution as an accident. The Urantia midwayers have assembled over fifty thousand facts of physics and chemistry which they deem to be incompatible with the laws of accidental chance, and which they contend unmistakably demonstrate the presence of intelligent purpose in the material creation. And all of this takes no account of their catalogue of more than one hundred thousand findings outside the domain of physics and chemistry which they maintain prove the presence of mind in the planning, creation, and maintenance of the material cosmos.
