mrrzy, best I can see, your post describes what you believe rather than demonstrating microbes to man type evolution. I found it strange that you describe single cells as an animal ?
The pictures I gave you links to show not what I believe, but what is known to science. Molecular genetics is demonstrating, has demonstrated, and continues to show you various ways to diagram the fact of microbe to humanity and to every other living thing. Best you see the pictures, that's why I linked to them for you.

Also, there are one-celled animals and there are one-celled plants. The one cell that gave rise to you wasn't an animal, though, it was just a cell. I wasn't calling all single cells "animals" but the ones whose ecosystem we are aren't plants or fungi, nor are they "us" genetically in the sense of being coded for by the union of our parents' gametes. They do not arise from the zygote that gave rise to us, yet are a basic part of us without which us wouldn't function or be.

We do have a lot of one-celled animals who live amongst our cells within our tissues. If the microbes that live in your skin stop working, you die because your skin stops working. If the microbes that live in your eyelash follicles die your eyelashes fall out. If the ones in your gums die all your teeth fall out, because those "germs" are what make your gums work to keep your teeth in, and so on.

But the microbe-to-all-life is well-established. Which of the diagrams do you not understand?
