    Universe 's the most abundant element is Hydrogen. In soil we measure pH to check its vitality for propagating plant life. Likely can we measure pH value for any planet to check potential to harbor life.

    That presupposes both that all life has the same sensitivity to pH, which we know is not the case, and that pH is uniform all over a planet, which it won't be.

    I'd think a change in pH - or an unexpected one - indicative of life already affecting geology.
