You are kidding, right?
The point is, if you can accept one prophet who makes inaccurate scientific statements, then you cannot condemn another for making inaccurate scientific statements…and let’s face it: Moses’ inaccurate statements, being codified into law that actually could (and probably did) get women KILLED, were a little more pertinent to life, religious thought and the beliefs of those who followed him than whether Brigham Young ‘rather thought’ (and “I rather think there are” are his exact words, by the way) that there was life on/in the sun/stars.
…and no world renowned scientist has come along to support MOSES’ statements. One HAS come along to support BY’s, however speculative and facetious you think his support may be.

By the way, I saw that documentary too, and his support for the idea may be speculative, but NOT facetious.
…by the way, the next time you claim that JS said, or wrote, that there were six foot men dressed like Quakers living on the moon, please provide the citation. That is, not a second hand 40 to 50 year old memory, but something JS wrote, or a speech to which more than one witness heard him say so. You know, something reasonable.
