You asked in your response to Harris: How it is that only one man in all the billions who've lived have had such an impact as Jesus?

This is like imagining how it is that Bill Gates is the richest man in the world ... someone has to be! Remarkable men are remarkable because we, the rest, note some remarkable trait they possess (and we even define what that trait is!).

And in secular science, many such people have existed…Aristotle, Galileo, Newton, Einstein, as examples. The impacts of their secular science discoveries have been astounding and directly and explicitly traceable to the remarkable inventions and thoughts that exist today. Indeed their thought process, discoveries and ways of knowing underpin both your and Harris's "facts" that support logical conclusions (indeed, even logic has been discovered by remarkable men, for example Euclid). Their discoveries about knowing and ways of knowing are the foundations of rational thought.

Such secular ideas have great numbers of followers (I am among them), just as you count yourself among Jesus's. One difference is that the secular rationalists do not preach divinity for Aristotle, Galileo, Newton, or Einstein.  (You have "solid" evidence of his existence, but not of his divinity.) They were just men, remarkable men, but just men with remarkable, wonderful-to-behold contributions to humanity's understanding of our universe.
