Galileo witnessed the revolution of the earth around the sun first-hand

Really? Galileo had a spaceship that allowed him to travel into space and actually observe this? Nobody has actually directly observed the motion of the earth around the sun. It is inferred from other observations, just as most theories and laws in science are.

Nobody has actually directly observed the motion of the earth around the sun.

I stand corrected, but would assert that his observations abd calculations were more direct than that of most people.
