After the universe began, innumerable rocks found places among an infinite number of stars, among them scattered different elements from which different life forms have likely emerged through a process similar to the evolution on Earth, but depending on local conditions. So, just like here, the occurrence of life in the universe is nothing more than a certain arrangement of matter being in the right place at the right time.

It is no coincidence that life on this planet evolved based on oxygen and water. Over the eons since Earth found a place orbiting our sun, these elements coalesced from the matter dispersed here, their abundance and stability being favored by the conditions caused by Earth’s position in our solar system. Eventually life sprang forth, first simple, and then, over time, gradually more complex as it evolved to compete in the ever-changing primitive environment.

As life has evolved, so has its perception. Because its origin is material, consciousness has developed over time, and it is as much a part of life as oxygen and water. Yet, even though it germinated from matter, it is immaterial and unique — a paradox that has baffled us since the beginning.

A conversation about death requires consideration of both life and awareness, so we next contemplate the evolution of consciousness to understand the condition of its end.
