Eli5, if the earth isn’t perfectly round, why does it seem that way in pictures from space?

I’ve always asked this question but people don’t really know or just answer in ways I can’t really understand it so I was just wondering if somebody here knows why?

The Earth is an oblate spheroid, which is a fancy way of saying it’s a ball that’s slightly squished in the middle.

But the amount the equator sticks out by is tiny by comparison of its size

The Earth is 43km wider at the equator than the poles, but it is 12714km wide at the poles. So the difference is only .3%

If the Earth were the size of a basket ball the bulge would be 2mm.

The point being if you looked at it you probably couldn’t tell without measuring it.
