Because we were made that way nobody actually knows why.
Yes, some nebulae can be seen with the naked eye, if you know where to look. They are better seen with binoculars, but in the right conditions some can be seen with the naked eye, like the Orion nebula, in the constellation of Orion.
uranus, though it can be barely seen from the naked eye.Neptune is too dim to see with the naked eye, but people with good eyes who know where to look can spot Uranus on a clear dark night (at its brightest it has an apparent magnitude of around 5.5).Saturn.Uranus should be visible for those with exceptional eyesight in areas with exceptionally dark skies as its maximum apparent magnitude is 5.32 and the faintest objects are those with apparent brightness around 7. Neptune never geta brighter than 7.78.
You won't see it every 20th of November, but in some years it is visible then. Lots of websites will tell you where and when to see it. If you don't see it then in a particular year, there will be other times of the year that you will see it. If it is visible then, you will be able to see it on other nights around then, as it can be seen for months when it is visible.
Yes, some planets such as Venus, Mars, Jupiter, and Saturn are bright enough to be seen with the naked eye on a clear night. They appear as bright, star-like objects in the night sky, without the need for a telescope.
There are currently no man-made objects visible from the moon, not even the Great Wall of China (see link below)Here is a quote from Astronaut Alan Bean (Apollo 12)..."The only thing you can see from the moon is a beautiful sphere, mostly white (clouds), some blue (ocean), patches of yellow (deserts), and every once in a while some green vegetation. No man-made object is visible on this scale. In fact, when first leaving earth's orbit and only a few thousand miles away, no man-made object is visible at that point either."The largest and only man made object to be visible to Neil Armstrong and for the matter any human would be THE GREAT WALL OF CHINA.For nothing else is visible to the naked eye.
With the naked eye, you can see some galaxies, like the two Magellanic Clouds, and the Andromeda Galaxy. The farthest objects visible in large telescopes would also be entire galaxies.With the naked eye, you can see some galaxies, like the two Magellanic Clouds, and the Andromeda Galaxy.

Some seals do.
because they are too far to see for the naked eye.
Visible objects in the sky include the Sun, Moon, stars, planets, satellites, meteors, and the International Space Station (ISS). Telescopes or binoculars can make some objects like planets and clusters of stars easier to see.

Because they still absorb and scatter some light.

The Great Wall of China?This is not true. From a low orbit of the earth, many artificial objects are visible on the earth, such as highways, ships, railroads, cities, crops, some buildings and the Great Wall of China.No man-made objects on the other hand, are visible at all after leaving the earth's orbit. NASA says, "The Great Wall can barely be seen from the Shuttle, so it would not be possible to see it from the Moon with the naked eye." From the moon, for example, even the continents are barely visible.

Mercury, Venus, Earth (of course!), Mars, Jupiter, and Saturn are relatively easily seen with the naked eye. I've read that Uranus is just barely visible to good eyes when sky-conditions are ideal. Neptune and Pluto are not visible without additional optical equipment.
