Carl Sagan is skeptic
Richard Lewontin, a evolutionary biologist wrote: "We take the side of science in spite of the patent absurdity of some of its constructs, in spite of its failure to fulfill many of its extravagant promises of health and life, in spite of the tolerance of the scientific community for unsubstantiated just-so stories, because we have a prior commitment, a commitment to materialism. It is not that the methods and institutions of science somehow compel us to accept a material explanation of the phenomenal world, but, on the contrary, that we are forced by our a priori adherence to material causes to create an apparatus of investigation and a set of concepts that produce material explanations, no matter how counterintuitive, no matter how mystifying to the uninitiated. Moreover, that materialism is an absolute, for we cannot allow a Divine Foot in the door."
Bart Ehrman, agnostic professor of religious studies at the University of North Carolina at Chapel Hill, revealed a naturalistic presupposition that is common to many historians. He said, “The bottom line I think is one we haven’t even talked about, which is whether there can be such a thing as historical evidence for a miracle, and, I think, the answer is a clear ‘no,’ and I think virtually all historians agree with me on that. Ehrman rejects the idea that any historical evidence could demonstrate a miracle because, in his words, “it’s invoking something outside of our natural experience to explain what happened in the past.” He arrived at a particular natural conclusion because he would not allow himself any other option, even though the evidence might be better explained by the very thing he rejects.
