This was about 3 670 000 000 BCE.
The purpose of creating life was to allow love to experience the perpetual fabric as it was created when she spoke. As an experience cyano-bacteria was novel but limited. And so we evolved.
It all started when three different micro-organisms got together to form the very first nucleated amoeba. Some simple oxygen-breathing bacteria took up residence in some stray bits of protein. Like the lichen created when fungi and algae fused, they two fused when they discovered a third prokaryote, another bacterium, which gave them mobility and sensitivity. The first bacterium formed the nucleus while the protein we now call mitochondria. The third microbe gave our cells their characteristic cilia.
Step by step groups of these cells got together to form multi-cellular structures capable of orchestrating their activities for the common good. It was only when we evolved to the chordata phylum that we crossed a threshold and the crowd actually developed an individuality which superseded the sum of the parts. To quote Lyall Watson in Lifetide: "The distinction between substance and form is as simple as the difference between the chemical composition of clay and the shapes into which that clay can be moulded. The substance of life is a small set of amino acids, but the forms are infinite. And in paging through the catalogue of possibilities, evolution has in our case hit on a form which is qualitatively different from others. It is relatively independent of the substance and has the capacity to be formative in its own right." (p115)
The chordata phylum dates back to about 500 000 000 BCE. All chordata are people.
By evolving bi-hemispherical brains we became aware of ourselves as separate entities, as people.
