Error: ” In any event, no knowledge whatsoever is required to reject supernaturalism.”
Correction: It only requires rejection of the evidence. It’s easy for the “natural” man to reject the things of God. But it only takes willful ignorance to believe that the universe created itself, especially after being shown the truth:
And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation.
For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water:-
Whereby the world that then was, being overflowed with water, perished:–2 Peter 3:4-6
Willful because it takes a desire to reject the evidence.
Here’s why it’s easy to reject the overwhelming scientific and historical evidence for the Genesis history:
And for this cause God shall send them strong delusion, that they should believe a lie:-2 Thessalonians 2:11
Actually it only takes pagan proclivities, and contrary to the satanic and literally self-righteousness of Ayn Rand’s preaching, an irrational mystical religion of spontaneous design, the universe itself designing life, a pagan “mystery” religion as old as 3,000 years:
Saying to a stock, Thou art my father; and to a stone, Thou hast brought me forth: for they have turned their back unto me, and not their face: but in the time of their trouble they will say, Arise, and save us–Jeremiah 2:27
You say the cosmic background microwave radiation supports the Big Bang belief, but that’s cherry-picking your evidence. I already pointed out, for example, that the Big Bang fails to fit the visible universe. In other words, the Big Bang requires FAITH, blind faith, in a universe made up of almost all fantasy props.
