“the major problem here is contamination. Even if we assume the things Hoover is seeing are fossilized life forms — and that’s not established! — can he show beyond a reasonable doubt that they are not from Earth? The meteorite in question is not a hard, dense rock, but actually very soft and friable (crumbly). Contamination in such a specimen is very likely. Hoover does not and really can not make a strong case that contamination is ruled out.
Another concern of mine was that he is basing a lot of this on the shape of the structures he sees… but looking like a microbe doesn’t make them a microbe! And Hoover goes farther than that. In an earlier work, he states flatly that these objects are fossils, and that they have bacterial structures inside them”
