Seeing an Air Gun Pellet Rolling Away

If there is no clear cut winner among the contending explanations, then even a very powerful kick may not convince us that the supposed source has independent reality. I have given examples from physics where very tiny kicks lead us to momentous conclusions about reality because we have no other explanation. The converse can also happen. For example, you may one day see terrifying monsters attacking you and then wake up. If the explanation that they originated within your own mind seems adequate, it would be irrational for you to conclude that there really are such monsters out there. This is what science is all about. Almost every single interesting phenomena in modern science is about explaining what we do see - light, rocks, stars
