The degree of curvature is so large that our eyes cant detect it from the ground level. Besides you need to cover a large tract of area to notice it!
For you to notice it ...you have to gain altitude.
On an aeroplane you will definitely notice the curvature.
Sit on rocket!! and you can notice the earths curve very clearly.
Whta you said would be possible on an astronomical body much smaller then the moon itself!

If you know trigonometry you can under stand. For several calculations we assume that a tiny part of a curve can be considered as a straight line. Our earth circumference is about 40,000 k/M long. At a time you can see a maximum distance of about 500 meters if it is in straight line. Therefore you can not notice the curve of the earth surface. But you go to beach and observe the ship going away from the shore. First you will see the bottom of the ship can not be seen. Gradually you can see the flag up to the last of your sight. It means it is going on a curved surface.

Take a giant beach ball.... put one finger on it.... now look at that one small spot where your finger is how could you possibly notice much of a curve on that miniscule spot... you cant and its the same as the earth, we are miniscule dots on the earths surface... when we walk around we cant usually, see or feel enough to be able to detect the earths curve. Its too gigantic... compared to us.

Because the earth is so huge, the curve so gradual. You do notice the curve if you see something a few miles away. It appears to sink down.

One word: Gravity.
Gravity, pulling us constantly to Earth's surface, makes it so that we cannot tell which way is up. We are actually sideways on the Earth. If there was none, those poor scientists in Antarctica would fall off the Earth! Nobody knows what Gravity is really, or why there is such a force. It's just there.

Because the earth is so large the curve is slight, you do notice it thought that is why you cannot see over the horizon line unless you are going in that direction and headed toward it.

If it were MUCH smaller you would, but it is so big that the curve is not seen in your point of view. In a jet at high altitude and no clouds, you can look out and see the curve but oh so slightly.

The Earth is so large that its curve is gradual enough we can't perceive it. You can see the curve from an airplane though!

Because it is not a small curve it is just a huge............ curve that we cannot just measure in a naked eye,but when u will watch the sea you can have some idea.

You can't notice it on the groung but at sea you can see a mast coming over the horizon first. This is why nobody have though the world was flat for thousands of years.
ps Columbus thought it was pear-shaped, thats why they laughed at him.
