Evolutionary Existence
At a fundamental level, human beings are the result of an amalgamation spanning millions of years of evolution.
Every thought, intuition, and facet of our existence was not constructed in a single day or even within a single lifetime. The construction of our existence reflects millions of years of evolutionary effort, much of which occurred beyond the scope of our awareness or control.
If that is the case, then what a person is, can become, and will be is a consequence, not a coincidence. While we may consciously and forcefully attempt to alter this, at a foundational level, we remain who and what we are.
