I think that is a far more fun way of looking at it! But the bacteria aren't the whole story - we also have our own cells, all doing their thing and all participating (even if bacteria in us are -also- participating). We're just groups of trillions of cells all working together to keep themselves alive and reproducing. And then we go work together with other blobs of trillions of cells, just to further that goal: survival of the cells. These groups of cells that started working together many, many billions of generations ago, are now looking at space exploration, colonising other planets, and wondering if there are other big groups of cells on other planets. There's no way they'd have gotten there if they'd kept living alone as single-celled organisms. That's fun to think about.
