The Urantia Book

Some one had asked about the human sources. and plagarism. I wanted to reply that the book tells us it is using human sources, more than 1,000 to help convey the revelation to us. Who better to understand our language and phonetics, than other humans?

5 - (0:12.11) In formulating the succeeding presentations having to do with the portrayal of the character of the Universal Father and the nature of his Paradise associates, together with an attempted description of the perfect central universe and the encircling seven superuniverses, we are to be guided by the mandate of the superuniverse rulers which directs that we shall, in all our efforts to reveal truth and co-ordinate essential knowledge, give preference to the highest existing human concepts pertaining to the subjects to be presented. We may resort to pure revelation only when the concept of presentation has had no adequate previous expression by the human mind.

6 - (0:12.12) Successive planetary revelations of divine truth invariably embrace the highest existing concepts of spiritual values as a part of the new and enhanced co-ordination of planetary knowledge. Accordingly, in making these presentations about God and his universe associates, we have selected as the basis of these papers more than one thousand human concepts representing the highest and most advanced planetary knowledge of spiritual values and universe meanings. Wherein these human concepts, assembled from the God-knowing mortals of the past and the present, are inadequate to portray the truth as we are directed to reveal it, we will unhesitatingly supplement them, for this purpose drawing upon our own superior knowledge of the reality and divinity of the Paradise Deities and their transcendent residential universe.

My final question is; the Urantia Book outright says that much of its scientific and historical knowledge is wrong and that the authors supposedly know that it's wrong.

I understand not giving the information if you're forbidden to but why give false information?

It is not so much false information as incomplete. The Revelaters tell us any info they give us will eventually become outdated as human knowledge expands...
