The world we are born into, live in, sleep in, and die from is a virtual reality created by our minds and assisted by our bodies. Our minds (souls) are eternal — they do not end when the body can no longer support life.
In this link the world we live in is a collection of tiny, subatomic particles that have no meaning in themselves. To create meaning out of this world we find ourselves in requires appropriate brain activity as well as the receptive actions of the five bodily senses.
The mind, or soul, is not created by the brain. It is of the same “stuff” as that which created it (God?). That is what we surmise at present. The link is worth watching several times to help the reader to start thinking outside of the classical physics mind-box.
