Bacteria in the human body: Roughly 3.8 \times 10^{13} (about 38 trillion).
Atoms in a single human body: Roughly 7 \times 10^{27} (7 billion billion billion).
Atoms in the known (observable) universe: Estimated between 10^{78} and 10^{82}.
Comparing 3.8 \times 10^{13} to 10^{80} is off by around 67 orders of magnitude—a number so vastly disproportionate that it defies everyday comprehension.
