I'm not talking about looking at a chalkboard full of equations, I'm talking about doing the math yourself and getting the same answers. [Equations like this](https://files.catbox.moe/13exq1.png). Try doing that equation for the Earth and your body's mass with a distance of 6.378 x 10^6 meters, but solve for mass (kg). It turns out that for you to be 90 kg the Earth has to have a mass of around 5.972 x 10^24 kg and you have to be 6.378 million meters from the Earth's center of mass. That's convenient since it matches up with a roughly spherical ball almost 8,000 miles in diameter.
