We are

Yesterday I had an idea for a new novel.  Last night I couldn't go to sleep because I couldn't get that novel out of my head.  The novel is about human colony ships flying out to earth-like planets that have no life and releasing various bacteria to start the terraforming process.

Today I found this fascinating article about bacteria will change your view of the world.  Apparently life is dramatically more complicated than we were taught in school.  How's this strike you:

"Strictly by the numbers, the vast majority — estimated by many scientists at 90 percent — of the cells in what you think of as your body are actually bacteria, not human cells."

It gets better.  The article is long, but well worth your time.

Apparently bacteria research will be a high-growth field for the next few years.
