How does knowing we are observing the 'afterglow' of the Big Bang change your perception of time and your place in the universe?

Understanding the CMB connects us directly to the earliest moments of cosmic history. It shifts our perspective from viewing human civilization as ancient to recognizing its incredibly brief flicker in a cosmic timeline stretching back nearly 13.8 billion years. This insight can foster a sense of humility, wonder, and a profound appreciation for the forces that have shaped everything around us. It encourages us to contemplate our fleeting existence against the backdrop of an immense and ancient cosmos.
