The human body hosts trillions of bacteria that collectively outnumber human cells (38 trillion bacteria vs. 30 trillion cells) and carry vastly more genetic material (3 million genes in gut bacteria vs. 20,000 in human cells), producing 95% of the body's serotonin and controlling immunity, digestion, and mood, meaning humans are fundamentally bacterial colonies with brains rather than just humans with bacteria.
