Every single atom in your body originated from a star that exploded billions of years ago. This is a hard concept to grasp, but think of it this way: In the begining of time there was nothing in the universe but Hydrogen and Helium (with just a small bit of other elements.) As gravity began to take ahold of clumped up masses of Hydrogen stars began to form. The first stars where super massive, most only lasting a few hundred million years. These first stars where the seeds of everything we now see and are aware of in the universe. The carbon, nitrogen, iron etc. in your body was all created from the first stars to light up the universe. As Carl Sagan said "We are star Stuff" All life in the universe would not be possible without stars.

Why do stars appear very small to us on Earth?

Stars appear small to us on Earth because they are extremely far away. The vast distance in space between us and the stars causes them to appear as tiny points of light in the night sky. Additionally, stars emit light that can be easily overwhelmed by the brightness of Earth's atmosphere and city lights, further contributing to their small appearance.

How big are the stars that you can see from the earth?

The stars visible from earth (except the sun) represent stars from the size of our sun to supergiants. How "big" they look to us is as much or more a function of their distance from us as it is their size. With good vision, on a clear night, the faintest stars we can see are about fifth magnitude. With a 70 mm telescope, that jumps to about 9th magnitude.
