Since games are very heavy programs so it can be very difficult to develop a game from the beginning . So we use game engines to make games which have some predefined rules and program which make game designing and development easier. Game engines are also known as physics engines because they use physics rules for graphics movement so games can look very real. Why we need a game engine? Games use real-world like graphics and simulation so it should be looking like a real world and the physics the game should be similar to the real world and game engine provides us that h physics engine which manages that motion, speed and acceleration of objects in-game, Games are also very highly graphics-intensive special 3D games and games engines lets us create them with ease without hard coding them all that's why we need game engine.
