I'm about 1m radius; a bacterium is 1um in radius; our sun is 700,000,000m in radius. So it's nearly a billion times my radius, and something like a thousand trillion times the radius of a bacterium. I don't believe we can't detect anything but purely dark matter planets passing in front of stars, and thus we can't rule out "life", only "planets". I also don't believe our theory is sufficient to distinguish "generic cloud of dark matter" and "cloud of dark matter in 'organic chemical' analogs", particularly because of our lack of sensitive gravitational measurements to directly test.
