You can sail and fly around the world, and we've traveled into space and looked back at the Earth and YES it is a sphere!

The ancient Greeks first figured this out by noticing the shape of the earth's shadow on the moon during a lunar eclipse. You can figure it out by going on a trip of a few hundred miles east or west and noticing what happens to the time of sunrise and sunset.

we can fly around it, look at it from space, see the curve of the horizon on the prairie or the sea. we can measure the angles of shadows if we want.
But best of all is that we have measured and mapped almost every square millimeter of the thing. Not only do we know the shape but we know the heights of the mountains and the depths of the oceans, and how fast they are changing.

Apart from the fact that space photos show us without any doubt, Columbus and all the other explorers after him would never have been able to navigate, since all navigation is based on a spherical world and planes and ships would get hopelessly lost if it was not a reality.

Additional information that indicates the Earth is not flat was noticed by people who noticed that as ships sailed away from port they seemed to disappear from the bottom up. The last thig visible was the top of the sailing masts.

It isn't. It is egg shaped. According to calculations, the earth is about 13 miles wider around the equator than it is pole to pole due to rotational inertia/acceleration forces.

Yes after all the evidence. ( The other posters have said it all ) There is still a flat earth society, it even has a website.

Actually, it's oblate spheroid.. It's something sientists or astronauts know better.. But i think they discovered it through the space explorations made by those space crafts...u

Well it's not perfectly spherical, but photos from space show that it's pretty close
