It never crossed my mind.
I remember doing an experiment at school to prove the Earth was a sphere.
Also observing the Moon through a telescope clearly shows it is a sphere.
I don't see why the Earth would be any different.
I've enjoyed sharpening iron with you, but it's a moot point really.
Whatever shape you believe the Earth to be it's still God's creation to be enjoyed.
I counter with:
1) A school experiment can't prove the Earth is a sphere (though happy to discuss if you think it can).
2) Observing the moon through a telescope only ever reveals one side, which can't differentiate between whether Earth's true shape is a ball or a coin.
3) The Earth is special, which is why it is different.
4) The philosophical purpose of heliocentricity is to cause the thinking that the Earth is not special, and allow for the atheistic relgions/worldviews of Big Bangism, Heliocentrism and Evolutionism (i.e. to invalidate the claims of scripture about Earthly things, so as to introduce doubt in the minds of men about spiritual things).
5) Earth is God's creation. But just as Evolution is a theory introduced to cause doubt about the legitimacy of God creating life as described in scripture, Heliocentricity is a theory introduced to cause doubt about God's special place for Man and the Earth in His Creation.
