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.
It hasn't ended. Natural environments like the grand Canyon are ever changing.

Yes, it seeks the Sea of Cortez, but little more then a trickle ever reaches it.
People visit the grand canyon to explore the beauty of it features and get a look at earth's natural creations before living organisms stepped foot on earth. if you ever go to the grand canyon on Niagara falls you will be so surprised of what earth has become and what it was. it is such a fantastic site.
It is in a constant state of change, but erosion is a slow and gradual process.
It is almost always the man made intention that creates that condition and that is done to maintaiin the ecology of the Canyon floor.
Yes, evil knevil tried ot jump the Grand Canyon on a motorbike. Robert "Evil" Kneivel never made any attempt go over the Grand Canyon in any vehicle, nor did he ever attempt any motorcycle jump across any major canyon. He tried (and failed) to take a steam powered rocket across Snake River Canyon, which is hundreds of kilometers from Grand Canyon. His son, Robbie, did jump 228 feet over a 2500 deep side canyon of the Grand Canyon, outside the national park.
