Yes, the Grand Canyon was once filled with water millions of years ago.
Yes, the Grand Canyon has been filled with water in the past. The Colorado River carved the canyon over millions of years, and at times in the past, the river has flooded and filled the canyon with water.
The material eroded from the Grand Canyon was deposited on a plain. Over many years, water eroded the plain creating a canyon later known as the Grand Canyon. The water kept weathering down the rocks until it came down to a lower level way below the top of the Grand Canyon. That is why today we have a higher and lower part of the Grand Canyon. Overall, the Grand Canyon started out as a plain and as many years passed water weathered down the rocks.
Washed downstream.
