The cave men living near to the Grand Canyon, millenniums ago.
Conorado searched for cibola and saw the grand canyon
low and behold
Coronado himself never saw The Canyon, but one of his captains, Garcia Lopez de Cardenaz, was led there by a group of Hopis.
No, but he is often given the credit because it was his expedition. He never saw the Grand Canyon. That honor belongs to one of his subordinates, Captain Garcia Lopez de Cardenas.
Not certain who is the "they" you are asking about, but no human had any choice on making the Grand Canyon a big thing. It was already big when the first humans saw it about 12,000 years ago.
