The world is round

At least I think it is.

Because I have never heard about a ship falling off the end of the ocean.

And there are horizons.

And I have seen photos from space.

But I have never been to space. So, I have to trust that someone has been up there. To accept what I see as true. We all have to rely on experts that the assertion they have made of the world is true.

It’s the same for car mechanics and climate scientists.
