My poll says Newton could have been replaced by a number of other people. However, his wealth allowed him to discover what a lot of other people couldn't afford to. If he was a member of the Order of Knights Templar as some report that could explain his secrecy.

Einstein received a Nobel prize for the photoelectric effect which is used in a tremendous amount of todays technology. His advocacy for the atomic bomb project in WWII makes him a very formidable scientist. The world would be very different if he hadn't been born but apples would still fall if Newton had been aborted.

Newton gave us the most important equation ever in Physics F = m x a. Much more important in our daily applications than Einstein E= m x c^2.

No scientist is truly irreplacable, even Einstein. Eventually, someone would have done what Newton did. Same for Einstein. They just were smart enough and got born earlier.
