in the Soviet Union, they have discovered a ray infinitely faster than light

Posadas just straight up making shit up lmao.

He does have a point that from a thermodynamic point of view: the kinds of compounds that give place to life are more energy efficient than inorganic ones, given the activation energy necessary and the right conditions are provided. Life is more stable than non-life, if life happens to exist in the first place.

Marxism and classic thermodynamics do have a lot of concepts in common, with Marx being very interested in advances in Thermodynamics in the 1800s and adapting some of its ideas to Marxist understanding (I learned this from reading Kohei Saito)

In an infinitely large and complex universe, life existing in multiple places is all but a certainty. Our universe isn't infinite (as far as we know), but it might as well be. That being said, it makes no epistemological sense to claim "life exists outside of earth", as it is an unfalsifiable statement unless we have mapped the whole universe out
