RE: Is the earth round or flat ? How do you know that its round ? who has proved it ?

whether to believe information you come across or not is solely your opinion. in that aspect, if you do not believe that earth is round (as shown in the satellite images) you shouldn’t believe the existence of any 

  1. place you’ve heard of, but not visited.
  2. person you’ve heard of but not seen him/her in person 
  3. and so on.
