Direct observation doesn't tell you much about relative size and motion

You believe that the Sun is much larger than the Earth，that the Earth is a roughly spherical planet that rotates on its axis every 24 hours and it revolves around the Sun once every 365 days.You believe that you were born on a particular date,
that you were born to two human parents and that each of your human parents was born on an earlier date.You believe that other human beings have thoughts and feelings like you do and that you are not surrounded by humanoid robots.You believe all of these things and many more,not on the basis of direct observation,
which can't, by itself, tell you very much about the relative size and motion
