For the first half of geological time our ancestors were bacteria. Most creatures still are bacteria, and each one of our trillions of cells is a colony of bacteria.
Bacteria are single-celled organisms. Bacteria are the model organisms for everything that we know in higher organisms. There are 10 times more bacterial cells in you or on you than human cells.
What's great about bacteria is you have a surprise every day waiting for you because they're so fast, they grow overnight.
Most bacteria aren't bad. We breathe and eat and ingest gobs of bacteria every single moment of our lives. Our food is covered in bacteria. And you're breathing in bacteria all the time, and you mostly don't get sick.

We actually have 10 times as many cells of microbes on us as we have human cells... We are literally a teeming ecosystem of microorganisms.
What you see is that the most outstanding feature of life's history is a constant domination by bacteria.
We are inhabited by as many as ten thousand bacterial species; these cells outnumber those which we consider our own by ten to one, and weigh, all told, about three pounds - the same as our brain.
My bacteria glow in the dark - no human being doesn't like that.
