It’s not just me who claims that. People who study rivers do too. It’s how the Grand Canyon was formed, for example. Most of the valleys in the UK were also formed by rivers, not glaciers.

And you do realize that the grinding, pulverizing, action of glaciers on the nutrient bearing rocks of entire mountains is also a necessary part of this process for providing land areas that are rich in nutrients that can host plant life.

Necessary? Really? So what glaciers were there in Australia? And how come the Nile Delta is so fertile? Or the Congo basin?
Both of my parents taught geography, so I literally learned this stuff at their knee.

Question-begging |
what fresh tard is this? |
Liquid water alone really wouldn't erode rock very well. If it were acidic, it would erode limestone by itself, but not most other rock.
But of course liquid water is never by itself on earth, and it erodes rock quite well by moving rocks, thereby causing abrasion and sometimes breaking rock.
Well-known processes that leave behind easily recognized river-eroded valleys.
