The markers that testify to the possibility of the living matter occurrence at exoplanets are considered in the context of the thermodynamically-grounded Life Origination Hydrate Hypothesis (LOHhypothesis). Just formation of DNAs from minerals is the key factor that makes possible origination of living matter; proteins are the side products of DNAs interaction with environment and of replication. DNAs and proto-cells originated under ground and (or) under seabed at 270 ± 20 K in solid ice medium from CH4 (or CH4-hydrocarbons), niter, and phosphate with liberation of O2, N2, and, possibly, NH3. Just the occurrence of these gases and their combinations in the planetary atmosphere and the above-specified underground temperature are the markers of the possible occurrence of living matter. CH4 formed from CO2 and H2 or is of nebular origin.
