No.

 

Because I can physically verify gravity exists. I just dropped a rock out my window and it fell down. I verified that the rock falls at approximately 9.8 m/s^2, consistent with both Newton and Einstein in non relativistic frames. Now, knowing that, I can apply simple physical laws to verify that a mass of sufficient size can not remain flat and stable. It would either break up, or it would collapse into a ball. And even if you tell me my models of gravity (i.e. that it is an emergent property of curved spacetime) are incorrect, any model you come up with must still behave according to the rules which we can determine from basic observation and math.

 

So if you are going to argue the Earth is flat, you might as well argue that 2+2=5. Any sufficient mass will form into a ball or break apart. It has no other choice.

It has been the doxa since the 17th century.

Bit of a ridiculous question as it is obviously round. If it was not round then it would be daytime in every country at the same time and night all at the same time which it obviously isn't

But what if Galileo was wrong and the church was right? The sun revolves around the earth.

 

Science has to be challenged.

Here is a demonstration of the geocentric model:

Well, FE's don't see it that way. Have you looked at the their model? The Sun, well that is, their Sun, doesn't illuminate the whole FE, just portions of it at any given time. That is, the Sun acts like a 'spotlight'. It is a FE ad-hoc solution with no observational or scientific backup.
