Time means nothing before the Big Bang. Nor is the idea of a "virtual vacuum" more lucid than the idea of the Trinity. It is just substituting mumbo jumbo for an idea that at least has some utility.

Why are there still plenty of unicellular organisms, but also organisms of increasing complexity? Any modification of the single cell, in a context of mitosis/meiosis as the means of reproduction, should have yielded nothing, or more single celled organisms. Apparently, there were plenty of niches for unicellular organisms to fill. How do we get to complex organisms?

By cellular differentiation,I mean nerve cells and blood cells and muscle cells and so on. These things only have meaning within systems. How do we get them incrementally to differentiate and assemble? If you do not have the right tissue for blood vessels, and cannot get the blood in there, and do not have capillaries to spread the nutrients, and do not have a heart muscle tied to a pulmonary system within certain parameters, and a nervous system to regulate the heart beat, etc., it all falls apart.
