Anaxagoras | Apollo
In 450BC, when, according to Voltaire (1764), Greek philosopher Anaxagoras claimed that the sun was not driven by Apollo, mounted on a chariot, but rather, based on the "evidence" of examined fallen meteors, and the reasoned postulate that moon light was reflected sunlight, that it was a hot or fiery stone, moving in a fifth element, in addition to the standard four elements, he called “aether”, which he conceived of as being in constant rotation and carried with it the celestial bodies, he was called an atheist, and had to flee.

In 2004, American deconversion philosopher American Christopher Redford, aka “evid3nc3”, via his YouTube channel name, engaged into the deconversion, from a devout Pentecostal Christian (2001) to that of an “evidence-based secular humanist” (2013), all of which is documented in his 2009 to 2012 “Why I Am No Longer a Christian” video series (see: Redford deconversion model); after which he self-identified as an “evidentialist”.

Quotes
The following are example quotes:

“A wise man proportions his belief to the evidence.”
— David Hume (c.1760)

“Facts are stubborn things; and whatever may be our wishes, our inclinations, or the dictates of our passions, they cannot alter the state of facts and evidence.”
— John Adams (1770), cited by Bertrand Roehner in Driving Forces [3]

“Trust a witness in all matters in which neither his self-interest, his passions, his prejudices, nor the love of the marvelous is strongly concerned. When they are involved, require corroborative evidence in exact proportion to the contravention of probability by the thing testified.”
— Thomas Huxley (c.1870), Essays Upon Some Controverted Questions [4]

“There is no evidence of a special life force, all of life on earth, including ourselves, is based on chemical processes and the four most common elements involved in the chemistry of life are hydrogen, carbon, oxygen and nitrogen, collectively known by the acronym CHON. We are made out of exactly the raw materials which are most easily available in the universe. The implication is that the earth is not a special place, and that life forms based on CHON are likely to be found across the universe, not just in our galaxy but in others. It is the ultimate removal of humankind from any special place in the cosmos, the completion of the process that began with Copernicus and De Revolutionibus.”
— John Gribbin (2002), “CHON and Humankind’s Place in the Universe” [2]
