        they are formed from collapsed nebula (areas) of gas/matter that clump together. this stuff was left over from the big bang.

        There are many interstellar clouds (containing hydrogen, helium, dust and gases) in the space, which come together and settle to form a star. Once they settle in, Hydrogen fuses to form helium and generates enough energy for the stars to shine.

        One way of interpreting this is — that there is a large amount of hydrogen in the space, andconsidering the high probablility of different hydrogen molecules coming together to form helium, and to facilitate this process, clouds containing hydrogen get together and settle to form a star! (The interpretation is my theory)

        Stars are born from cloud rich in hydrogen gas that you can find in nebula. You can find nebula only in galaxy.
