Number of cells in the human body, and synapses in the human brain

A current estimation of human total cell number calculated for a variety of organs and cell types is presented. These partial data correspond to a total number of 3.72 × 10^13, or
3.720. cells.

In humans, there are about 200 different types of cells, and within these cells, there are about 20 different types of structures or organelles. 2

If we suppose that the first unicellular life forms emerged 3.5bi years ago, that is 3.500.000.000 years, then there would have to be an average increase of 1.062.857 cells each year, or 2912 cells per day, or 121 cells per hour to get the number of cells of the human body. Each of these cells would have to differentiate to form the different tissues and organs, the emergence of a signaling language,  right cell signaling at the right place, at the right moment, to provoke cell movement and cell proliferation to the right place, to form the right organs and tissues, and interlink them correctly in a functional way.

The human central nervous system (CNS) is the most complex living organ in the known universe. 6  Each synapse functions like a microprocessor, and tens of thousands of them can connect a single neuron to other nerve cells. In the cerebral cortex alone, there are roughly 125 trillion synapses, which is about how many stars fill 1,500 Milky Way galaxies.  The human brain is often considered to be the most cognitively capable among mammalian brains and to be much larger than expected for a mammal of our body size. 4  We find that the adult male human brain contains on average 86.1 +/- 8.1 billion NeuN-positive cells.   The total myelinated fiber length in a human brain varies from 150,000 to 180,000 km in young individuals. The total number of synapses in the human neocortex is approximately 1,5 x 10^14 (0.15 quadrillion), that is 1500000000000000 synapses. The brain has more switches than all the computers and routers and Internet connections on Earth. 5 These connections should reveal a great deal about how the brain works, for while a single nerve cell may be enormously complex, it is in the massive networking of these many neurons that the brain’s fantastic processing and cognitive powers are likely to emerge.

According to mainstream science, Flatworms are the earliest known animals to have a brain, and supposedly evolved 500 mio years ago.
It would have had to produce 3.000.000 synapse connections per year, or 8200 new synapses per day, or 342 per hour. These synapses would have to make the right synaptic connections to form a functional nervous system.
