* Mountains have always existed. They are natural formations, not things that were "created" or "discovered" in the way a new species of animal might be.
* Early humans lived near mountains. It's likely that people have been aware of mountains for as long as humans have existed.
* The concept of "discovery" is subjective. What constitutes a "discovery" depends on the context. Did early humans consider a mountain a "discovery" or simply a part of their environment?
Instead of asking who discovered the first mountain, it's more interesting to consider:
* How mountains have been perceived throughout history. Mountains have often been viewed as sacred or dangerous places.
* The role of mountains in human cultures. Mountains have influenced mythology, religion, art, and literature.
* The challenges and opportunities that mountains present. Mountains are home to unique ecosystems and offer challenges for climbing and exploration.
