They did not.
Early cave art is actually very sophisticated. They often used natural shapes in the rock to make the animals they drew look 3D.
Cave painting artists used a form of perspective by depicting things closer to them larger in size, while things farther away were smaller. This technique gave the illusion of depth and distance in their paintings.
Cave paintings provide valuable insights into the prehistoric societies that created them, including their daily life, beliefs, and environment. Historians can use cave paintings to understand ancient cultures, their artistry, and possibly their communication systems. They help paint a picture of the past that complements other archaeological and historical sources.

Explorers discovered ancient paintings inside the cave. I plan to go spelunking in that limestone cave over the weekend. The bat colony inhabits the cave near the mountain.
Cave men used fire for heating and cooking. They would create fires using materials such as dry grass, sticks, and rocks to produce heat and cook food.
Cave men likely used fire for heating and cooking. They probably started fires by rubbing sticks together or using flint to create sparks, and then they would have used the fire for warmth and preparing food.
one point perspective started in the 15th century.
Artists didn't need to use perspective or create the illusion of depth.
The use of perspective changed. Central perspective was invented early in renaissance.

Perspective is a method that makes a drawing or painting look three-dimensional. Artists had tried to use perspective before, but Renaissance artists perfected it. Using perspective, objects in a scene appear to be at different distances away from the viewer. The result is a more realistic image. To make their paintings more realistic, artists had also used a technique called chiaroscuro. Chiaroscuro softened edges by using light and shadows instead of stiff outlines to separate objects. In Italian, chiaro means "clear or light," and oscuro means "dark." Chiaroscuro created more drama and emotion in a painting.
In the Renaissance artists began to show perspective in their paintings and used better paints and glazes on canvas. Most mid evil art is flat, on wooden panels using egg tempra(this is why they look green today) and didn't use perspective. Artists began to use focus to draw the eye to an area of the painting. The Last Supper is a perfect example of this use of focus and his use of perspective.
The artists use of blue in the painting gave it a fine nuance that the other painting didn't have.
Artists did not yet know how to use perspective and so the art appears flat.
Artists have employed the use of perspective for eons, however wobbly. Atmospheric perspective (where we see mountains receding into the mist and fog) has been used in Chinese and Japanese painting as well as in that of Northern Europe and Scandinavia. The person to really nail down linear perspective was engineer/architect Fillipo Brunelleschi. He is the one who came up with the iron-clad laws of vanishing points and perspective grids. This forever changed drawing and painting.
