Contrails consist ofice particles that form or nucleate around the small
soot or aerosol particles in the exhaust hases. The contrails are
formed when the relative humidity increases because of the mixing of
warm and moist exhaust gas with colder and less humid ambient air of the
atmosphere. Contrails become visible roughly about a wingspan distance
behind the aircraft. Contrails can be formed by propeller or jet
turbine powered aircraft. (WALTER M. WASHABAUGH, Colonel, USAF

Prove that there isn't enough matter in jet exhaust to form these contrails.
