Then why don't kids in science class debate whether or not the Earth is the center of the solar system?
Because nobody believes that..
The Earth Is Not Moving
Guy Consolmagno Will Not Deny Geocentrism
There are some. A strictly literal reading of the Bible requires it. God stopping the sun and making it go backwards requires it:
Joshua 10:12,13
12Then spake Joshua to the LORD in the day when the LORD delivered up the Amorites before the children of Israel, and he said in the sight of Israel, Sun, stand thou still upon Gibeon; and thou, Moon, in the valley of Ajalon.
13And the sun stood still, and the moon stayed, until the people had avenged themselves upon their enemies. Is not this written in the book of Jasher? So the sun stood still in the midst of heaven, and hasted not to go down about a whole day.
Obviously not possible in a heliocentric model.
Then there's
2 Kings 20:8-11
8And Hezekiah said unto Isaiah, What shall be the sign that the LORD will heal me, and that I shall go up into the house of the LORD the third day?
9And Isaiah said, This sign shalt thou have of the LORD, that the LORD will do the thing that he hath spoken: shall the shadow go forward ten degrees, or go back ten degrees?
10And Hezekiah answered, It is a light thing for the shadow to go down ten degrees: nay, but let the shadow return backward ten degrees.
11And Isaiah the prophet cried unto the LORD: and he brought the shadow ten degrees backward, by which it had gone down in the dial of Ahaz.
Also not possible in a Heliocentric model.
And there are still some people who hold to the strictly literal.
The interesting thing is that a geocentric model isn't impossible...You can construct a model with the frame of reference of the earth stationary and everything moving around it, but the math is insane. It's the equivalant of saying a car is stationary and the road is moving under its wheels. Possible to describe mathematically, but very difficult to do.
