Yop, the point is this: do you have any reasoning other than that people told you so for any of your beliefs, such as your belief that the Earth is round, that Mars has a lower surface gravity than the earth, etc.? If not, kindly stop arguing it, as you will never convince anyone of anything, and have no business even debating the issue. If so, then please provide the reasoning, or else don't be surprised when nobody takes you seriously.
