This is as good a prĂ©cis of the difference between science and religion as you’re likely to ever encounter.
When an engineer grabs his computation pad and begins to analyze a problem, whether it needs a dozen pages or 100-pages, every single line has a documented pedigree — a long train of observations, tests, hypotheses, more tests, public analyses — from Pythagoras’ meditations on right triangles to Einstein’s speculations on the photoelectric effect.
Your neighborhood Holy Man can’t even prove that Our Invisible Friend is real. This is why science and engineering went from Isaac Newton’s encounter with the apple to the moon in ~ 350-years, and religion has nothing to show for itself but Niagaras of bloodshed.
