Joseph,
Would you eat a piece of meat that the author of one of your sources had told you was kosher, when you yourself had seen it taken from the carcass of a pig?
None of the people you cite lived long enough to hear of the discovery of the cosmic background radiation, which proved beyond any doubt (1) the big bang, and (2) the ancient universe. We cannot conjecture what they would have said had they lived into the 1960s and studied the data carefully.
