Finally, a worthy debate! I dont think we can know how aliens are or how they reproduce/interact, but they can have their own version of oxytocin/other similar chemicals to produce love, also, the whole "care for their young" its an evolutionary response, we, as a species need to care about our young ones, because we need to survive and make sure the next generation is safe... I just dont relate love with entropy, love, even if it is a cosmic force or it is conected to the creator it wont be the opposite of entropy, entropy is the force that makes matter go into chaos, decay, so it can reform into new and different forms, it is just a transition, it is not evil nor good
