ants are neither two-dimensional creatures nor two-dimensional cognitive abilities. If you put an ant on a piece of paper, when the ant crawls to the edge, you can see that the ant is also afraid of falling, and the tentacles on the ant's head can be tested up and down, left and right, which shows that the ant has spatial perception ability. There are also ants that produce a large number of winged ants in the breeding season every year. These ants usually leave their nests and fly to the sky to participate in the dance near dusk, attracting the opposite sex to return to the ground to mate. After mating, the male ants will die, and the female ants will bite off their wings and choose a suitable place to nest and lay eggs. This may be because some ants reproduce in this way, but it is enough to show that they are three-dimensional creatures and have three-dimensional cognitive ability from the fact that they can grow wings and fly to the sky to find the opposite sex, and then return to the ground to mate and reproduce. If people don't have smart brains to develop science and technology, they will crawl on the ground like ants.
