How did the first cell of the very first human being emerge. It is a long story. The whole universe emerges from an infinite yet infintesimal reality called energy or spirit. Billions of years later after the origin of the universe, the human appears. He/she must also have started from a single cell like we now do.
How then can anyone say that anything in us is separate from our totality? How can anything be seaparate and apart from the totality of the whole universe?
