Is it true that it didnt rain in calama chili for 400 years?

It is not accurate to claim that it did not rain in Calama, Chile for 400 years. Calama is located in the Atacama Desert, one of the driest places on Earth, but it does experience sporadic rainfall. While the region may have long periods without significant precipitation, it is not correct to state that it did not rain at all for four centuries.
