Everyone asks why. Young children ask why incessantly! They have a good reason to ask why, with very limited knowledge and life experience they honestly have the best of reasons to ask why. They know little and want to know everything. The remainder of us ask why for a variety of reasons.
Like everyone else, I ask why when I need to learn the answer to something I am not knowledgeable of. I also ask why when I’m questioning something that seems impossible or unbelievable, or why does something exist which really shouldn’t. Something like, why the divided state of our nation? We have the best of everything like freedom, prosperity, opportunity, etc. yet we have division, controversy, anger, distrust, and so on. Why?
Why and how do people sometimes do things that seem to have no reason or plausibility ? Something horrible and inhumane like killing others.
