It doesn't follow - the type of consciousness we experience could be different. Though if you were saying that it's absurd to call single cell 'conscious' in the sense that human brains are, then I agree.
As for your analogy, it is true that microorganisms can perform wonderful feats, but it is a bit misleading to equate that to general intelligence. It is like saying a compiler is smarter than a programmer, because its design incorporates tricks the human may not know. (The bacteria being "designed" by the trial-and-error process of natural selection, rather than an intelligent entity, of course.)
