"Here we are, we're alone in the universe, there's no God, it just seems that it all began by something as simple as sunlight striking on a piece of rock. And here we are. We've only got ourselves. Somehow, we've just got to make a go of it. We've only ourselves"

John Osborne's quote records an existential perspective on the nature of human existence, stressing the extensive isolation and duty of humanity in a relatively indifferent universe. His words reflect a sense of existential privacy, highlighting the belief that human beings are alone without the oversight or existence of a magnificent developer. The assertion "there's no God" recommends a secular, perhaps atheistic worldview, where significance and function are obtained internally instead of being externally enforced by a greater power.

The imagery of "sunshine striking on a piece of rock" alludes to the scientific, perhaps evolutionary, origins of life-- an easy yet powerful occasion resulting in the intricate advancement of awareness and civilization. This point of view underscores the randomness and serendipity of existence, highlighting how life as we understand it could have emerged from natural phenomena with no fixed strategy.

By stating "We've just got ourselves", Osborne moves the focus from external sources of purpose to internal ones, suggesting that mankind must take complete duty for its actions, worths, and fate. This self-reliance is both difficult and liberating, putting the onus on people and societies to forge their paths and develop significance in their lives. This concept aligns with existentialist philosophy, which presumes that people are responsible for imbuing their lives with meaning in a disinterested and disorderly universe.

The repetition of "We've just ourselves" works as a poignant suggestion of the cumulative and private duty that accompanies this existential realization. Without the assistance of a deity or the convenience of predestined function, mankind must face its freedom and the intrinsic obstacles that included it. Ultimately, Osborne's quote requires resilience and decision, advising us to accept our solitary yet effective role in shaping our lives and the world around us.
