Are human beings the supreme creed because of their intellect?

Rationalism you equate with "Intellect" ... is neither Civilization, nor the sign of human Supremacy over other living things ... Because, Reason invariably tends to Barbarianism, when we place Logics above Truth, or Expediency, above what be Right. Because humans are much more than just Social or Rational Mammals. But "Intellect" in State of the Human "Mind" ... Granted by God to Humans, as "Definitive Nounal Concepts" of Existential Reality... Encompasses The Created Totality ... while Reason cannot see, beyond the Physical ... Thus, Logic is just one, of the Nounally defined human Awarenesses!

The distinct Awareness of the "Human Mind" ... Makes Humans the Supreme Creed in Creation and distinguishes Humans from Animals, who live out a Physical and generally Pragmatic existence.

In my mind, there is no absolute answer to your question. We're all just space dust.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
