Here is a video for your consideration. Since the earth is flat, there has to be more land in the extreme south of earth (Antarctica). Here is a video for your consideration. Notice that this land is free of ice and snow except in the higher elevations. So, where would it be this warm when all around is snow 12 months of the year?
We know that there is more ocean in the southern hemisphere but you can’t photograph that and say, “Here is new ocean!” It doesn’t make sense but with land you can do this. What you can do with the ocean – to prove that there is more – is to sail in a ship. For example, we are given the distance between the southern continents, so, if you have a sea-worthy yacht, see if the journey takes longer than what it should. If you find out that it does, it tells us that the earth is much larger than what it is. If you are rich and have your own jet, fly the distance from New Zealand to South America – directly. But before you do, you better have plans to be sure you can land on some island on the way. The reason for this is, that if you gage the fuel with what you are told the distance is, you’ll come up, perhaps, thousands of miles short.
