Hello. I am new here. I am interested in the flat earth based on youtube videos and conversations with others. But I have to get over one thing. I just cruised from Miami to the Virgin Islands. And on the ship my whole family could see the curvature of the earth. They commented on it many times. I saw it myself. If the earth is flat how could we see the curvature of the earth on a ship with our eyes. I am not talking about pictures with a camera. We saw the curvature with our eyes.

What do you say about that?
