Life's Origins: Did Aliens Do It? (A Thought Experiment)

This paper explores the probability of life spontaneously arising on Earth, calculating the information needed to build a protocell within the time available. It concludes that while theoretically possible, the conditions are extremely improbable, raising the question of external intervention (panspermia or, as the author colorfully notes, aliens).

Identified Weaknesses

Highly speculative

The paper relies heavily on estimations and theoretical calculations, acknowledging high uncertainty in key parameters like prebiotic entropy and protocell complexity. The 'terraforming' aspect is entirely speculative and presented for thought-provoking discussion rather than scientific evidence.

Oversimplification of complex processes

The paper uses simplified models, such as rate-distortion theory and Kolmogorov complexity, to capture complex biological processes. These simplifications may miss crucial nuances or unknown emergent properties.

Lack of empirical evidence

While the paper uses some geological and chemical data, it lacks direct empirical evidence for the emergence of life. The core argument relies on probabilistic reasoning and computational models.

Anthropic Bias

The paper acknowledges, but does not fully address, the inherent anthropic bias in observing life's existence on Earth and the fact that we're around to wonder about it.

Rating Explanation

This is a thought-provoking paper that explores a fundamental question in a quantitative, albeit speculative, way. The methodology is sound within its acknowledged limitations, but the lack of empirical evidence and reliance on estimations limit its scientific impact. The discussion of terraforming is presented as a speculative thought experiment, which is acceptable but should not be misinterpreted as scientific evidence.
