Answer 1

It indirectly states that the universe knows about mankind but doesn't feel a sense of obligation to care and shows that humankind is self-centered to think that the universe should care for their existence. Not only this but It reveals humanity's helplessness against external forces.

Answer 2

Answer:

The irony reveals naturalistic themes here establishing how nature is superior and governs the character of the human being, which is one of the main characteristics of naturalistic themes.

Explanation:

The idea that the environment determines and governs the human being is clear in this quotation.  

The human being tries to get the attention of the Universe, claiming "I exist!" , but the Universe does not seem to care about its insignificant existence, and feels that it has no obligation to this creature.
