Small is big.  Nanotechnology is the new marketing buzzword.  Event two of the COVID-19 vaccines are produced using nanoparticles.  But God was into nanotechnology from the very beginning, building life on a series of biochemical "nano-machines".  A molecule of water is about three tenths of a nanometer wide.  A nanometer is one billionth of a meter.  The water molecule also has a slight positive and a slight negative end.  Without this small separation of electrical charges, life would not be possible.  There are many other examples of such miniaturization in biological cells.  But where did these careful, finely tuned nano-machines come from?  Uplook Magazine May 2006, p.9.  References:  I.
