Oxygen is used in liquid-fueled rocket motors as a combustion product, usually in conjunction with liquid hydrogen as well. In space, Oxygen is extremely thin at extreme altitudes, and it only occurs in space at the molecular level. It isn't enough to sustain the combustion of a liquid-fueled rocket motor once it enters the upper atmosphere without being fed liquid oxygen.
Rockets need to carry their own supply of oxygen because they travel through the vacuum of space where there is no atmosphere to provide oxygen for combustion. By carrying their own oxidizer, such as liquid oxygen, rockets can generate the thrust needed to propel themselves forward.
Rockets need oxygen to facilitate the chemical reaction for generating thrust. By combining oxygen with fuel in the combustion chamber, rockets produce the hot gases needed to propel the vehicle through space. This enables rockets to overcome the lack of atmospheric oxygen present in space.
Rockets are used to get to the moon because they provide the necessary thrust to escape Earth's gravity and enter into lunar orbit. They carry the spacecraft and its payload, including astronauts, to the moon. Rockets also provide the propulsion needed to perform maneuvers such as entering lunar orbit and landing on the moon's surface.
The first part is simple, you need three things for a fire: Heat fuel Oxygen You get liquid oxygen that is mixed in with the just fuel before it ignites.
Fire needs oxygen in order to burn, and there is no oxygen in space, so rockets must take oxygen with them.

Some rockets, such as liquid fuel rockets, carry liquid oxygen (LOX) as an oxidizer in a separate tank. The LOX is then mixed with the rocket's fuel and ignited to create thrust. Other rockets, like solid fuel rockets, have an oxidizer mixed into their solid fuel composition.
The force of energy and oxygen propells bottle rockets.
because in outer space there is no oxygen
A rocket engine carries its own supply of oxidizer, which provides the oxygen needed for combustion to occur. This allows rockets to operate in the vacuum of space where there is no external source of oxygen.
Water rockets use water and air modern rockets use thrust and oxygen.
