How do you know? Because you have been told by someone?

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.
