At certain times of year, several meteoroids collide with the Earth’s atmosphere. This happen when Earth goes through a region of space that contains a lot of rocks and dust. This debris come from the passage of a comet that breaks up as it comes near the Sun ejecting a lot of dust and chunks of rock in its path. If the comet's orbital path intersects with that of Earth, then the swarm of rocks and dust scattered over the comet entire orbit will then collides with the Earth’s atmosphere. This event will result in what you called a meteor shower. Large numbers of meteors observed in a particular part of the sky are named for the constellation in which they appear to originate. For example, the Aquarids seem to come from the constellation of Aquarius (July 15- August 15 - Delta Aquarids), Leonids will appear to originate in the constellation of Leo (November 15-20), the Perseids from Perseus (July 25 - August 18) and the Orionids from Orion (October 16-27). Scientists (astronomers) used the name of the constellation it appears to come from to name them for easy reference. Meteor showers occur on about the same dates each year.
Therefore, a falling star or a shooting star has nothing whatsoever to do with a star. It is just another name for a meteoroid (interplanetary debris) that burns up as it enters the Earth's atmosphere. That is, air friction vaporizes them into the white-hot streaks of light. This visible path (streak of light) of a meteoroid is a meteor. Thus, shooting stars or the falling stars are meteors.

On Earth however, we have what is called daylight. Daylight is the time after sunrise and before sunset and is the condition of brightness created by the rays of the sun. This brightness is a combination of all direct and indirect sunlight. Daylight produces a visual sensation that allows us to see our entire surrounding (environment) in its form and colors, such as, the beautiful blue sky, puffy white clouds, flowers of all variety and colors, as well as, all the other beautiful objects surrounding us in our day to day life in our environment.
The earth is surrounded by a gaseous envelope called the atmosphere. Apart from the layer of gases , the atmosphere also contains moisture (water droplets) and dust particles. The light from the sun hitting these "obstacles" in the atmosphere (air) causes light to reflect and refract. The reflected (bouncing off) and the refracted (deflected when the light go through a substance) rays illuminates our surroundings allowing one the power to perceive by sight (see) the world in its splendid colors.
Space on the other hand, is black in spite of the numerous star presence. Space contains comic dust and elements like hydrogen and helium atoms for every cubic meter (or per cubic centimeter). This however means that its gas molecules density is so low that it is practically nonexistent - a vacuum. This means that all the light in space will travel in a straight line without any dispersion (refraction and reflection). This is similar to a laser pointer where you see the spot but not the beam. This is due to the fact that the light does not go to where your eye is, it is not dispersed. The light goes directly to the spot where the pointer is pointing. Therefore, you can only see spots of lights in space from its source but not the illumination of its surroundings. Light makes its way to our eyes because you are looking at something bright but the light itself is not scattered. Space has no atmosphere (almost a perfect vacuum) which means there is nothing for the light to become "scattered" on. As such, there are no colors for you to see and therefore outer space always looks black.
