Maybe that's because many secular scientists view faith as the enemy of science. The arrogance of many scientists is what sticks in my craw. Many say that the realm of the spirit is something that is beyond the ability of science to measure and observe, and hence they simply do not know and cannot make definitive statements about the things of the spirit. But other scientists have demonstrated an arrogance that since God and the things of the spirit cannot be dragged into the lab for observation and experimentation, they are inconsequential, if they exist at all. Science has been used as a means and a pretense to "eradicate the myth and superstition" of religion from the human consciousness -- at least by some, and Sagan tended toward this perspective. A little more humility on the part of the scientific community about the limits of science, and what scientists don't know, would be helpful.
Not without plenty of historical (and present-day) justification.
