Answer to Question 1

FALSE

Answer to Question 2

Aristotle correctly concluded that if the heliocentric model were valid, we should be able to see the closer stars show parallax shift over a six-month interval as we went from one side of the Sun to the other. He failed to detect any such shifting, and thus concluded we could not be moving. Now, with powerful telescopes, we do measure the parallax shifts of the nearby stars, but this is much too tiny to be detected with the naked eye by the ancient Greeks.
