Does anyone know that other planets aren't still partially molten, as well?
Jupiter has a mean radius of 43,440.7 miles (69,911 kilometers), about a tenth that of the sun. However, its rapid rotation — it spins once every 9.8 hours — causes it to bulge at the equator, where the diameter is 88,846 miles (142,984 km). In contrast, the diameter at the poles is only 83,082 miles (133,708 km). This stretched shape is known as an oblate spheroid.

Where do you get that info? Have you seen it?

No math, no theories, the Earth is doing all the proving.
Who says that we aren't on a flattish disc that is spinning?

That's not true. I except truth. All data considered. I just haven't been convinced the earth is spherical. Not convinced it's flat either.

Ok but that doesn't prove globe earth. The same data is accepted by flat earth folks.

The ancient greeks would have gotten the same results on a flat earth with the sun much smaller and much closer than we are "told" it is today.

That's not true. I myself have proved that wrong.

One of the best documented methods for determining the Earth's roundness was first performed (to our knowledge) by the ancient Greeks. This was achieved by comparing the shadows of sticks in different locations. When the sun was directly overhead in one place, the stick there cast no shadow. At the same time in a city around 500 miles north, the stick there did cast a shadow.
If the Earth were flat then both sticks should show the same shadow (or lack of) because they would be positioned at the same angle towards the sun. The ancient Greeks found the shadows were different because the Earth was curved and so the sticks were at different angles. They then used the difference in these angles to calculate the circumference of the Earth. They managed to get it to within 10% of the true value – not bad for around 250 B.C.
