I have no doubt that we have been to the moon. This question has nothing to do with a moon landing hoax. But, there are two quotes from two different astronauts regarding the size of the earth as viewed from the moon that are puzzling to me. Both quotes talk about how small the Earth looked. Shouldn’t the Earth look very large when viewed from the moon
It suddenly struck me that that tiny pea, pretty and blue was the Earth. I put up my thumb, shut one eye and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small. — Neil Armstong
As we got further and further away it [the Earth] diminished in size. Finally it shrank to the size of a marble, the most beautiful you can imagine. That beautiful, warm living object looked so fragile, so delicate that if you touched it with a finger it would crumble and fall apart. Seeing this has to change a man. — James Irwin
I know the term large is subjective, but still, the comments seem off. Please let me know what I’m missing.

The moon is very far from Earth so it would seem that small from the Moon.

From the moon, the earth would appear to span across about 2 degree of sky. If you hold your thumb a few inches in front of your face (or your facemask if you are on the moon), your thumb will block about two degrees of your field of view (Armstrong mentions closing one eye because his thumb is close enough that the different perspective between his two eyes is significant). So there doesn't seem to be anything too surprising about these statements.

You can get a rough idea of how large the Earth appears from these two photos:
It's not quite that large, is it?

The Earth is 4 times the diameter of the Moon. The Earth viewed from the Moon will therefore appear 4 times as large as the Moon viewed from the Earth.
The Moon is easily obscured by a thumb at arm's length.
Now bring your thumb closer (because you can't fully extend your arm in a bulky space suit) and put on the biggest pair of ski gloves you can find.
It is not a great stretch of the imagination to think your thumb would obscure something 4 times the size of the Moon.

If you reduce the scale of the Earth to make it the size of a tennis ball, then the moon would be about the size of a ping-pong ball, and the moon would be about 7 feet from the Earth.
So you can get a good idea of what the moon would look like from the Earth: Get a tennis ball and ping-pong ball set them up 7 ft (2 m) apart put your head next to the ping-pong ball, and the tennis ball will look about the same size as the Earth would look on the moon
https://www.youtube.com/watch?v=GCTuirkcRwo
Now hold up your thumb, cover the tennis ball and imagine "on it [is] everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives".

Watching the moon from earth, it seems to be larger at the horizon than at the sky. This means that optical illusions may play a role here, too. The lack of reference objects or maybe the different shape of the horizon on moon may also contribute to the apparent size of earth.
