Interplanetary migration hypothesis falsification

The interplanetary migration hypothesis posits that a technologically capable population migrated from Mars to Earth, transmitting a cultural narrative of Martian megafloods that persisted as terrestrial flood myths Verified Answer #4Verified Answer #1. This premise is formalized through several frameworks, including the Litho-Cultural Migration Hypothesis (LCMH), the Exoplanetary Semiotic Transfer Hypothesis (ESTH), and the Martian Deluge Transmission Hypothesis (MDTH) Verified Answer #4Verified Answer #1Verified Answer #2. While these hypotheses are structurally testable, they are robustly falsified by biological, geochemical, and information-theoretic constraints Verified Answer #4Verified Answer #5.

Biological and Physical Constraints

The physical stresses of interplanetary transfer present a primary barrier to the migration of complex organisms Verified Answer #4.

• Microbial-Technological Disparity: While certain extremophilic microorganisms can survive the high-pressure ejection from a planetary surface, the impact pressures exceeding 3 GPa required for such a launch are lethal to all known vertebrates and hominids Verified Answer #4.
• Homochirality Paradox: Life on Earth is strictly homochiral, utilizing L-amino acids and D-sugars Verified Answer #4. Martian life, evolving independently under unique geochemical conditions, would likely possess a different chiral signature or a racemic baseline Verified Answer #4.

Geochemical and Isotopic Falsification

Planetary bodies possess unique isotopic "fingerprints" established during their formation and atmospheric evolution Verified Answer #5.

• Oxygen and Chromium Isotopes: Mars and Earth exist in distinct isotopic reservoirs Verified Answer #5. Martian rocks exhibit a distinct Δ17O signature of approximately +0.8‰, whereas the terrestrial fractionation line is approximately 0‰ Verified Answer #5.
• Hydrogen Ratios: Data from the Curiosity rover indicates that the Deuterium-to-Hydrogen (D/H) ratio in the Martian atmosphere is roughly six times higher than Earth's Standard Mean Ocean Water Verified Answer #3. Any biological entity developing on Mars would permanently incorporate this extreme D/H signature into its tissues, such as bone and tooth enamel Verified Answer #3.

Information Theory and Cultural Transmission

The hypothesis that a "memory" of Martian floods could survive for millions of years is contradicted by the laws of information stability Verified Answer #2.

• Signal-to-Noise Barrier: Oral traditions function as noisy channels subject to linguistic drift and memory decay Verified Answer #2. Anthropological research indicates the maximum reliable temporal retention for oral traditions regarding environmental events is approximately 7,000 to 10,000 years Verified Answer #2Verified Answer #6.
• Temporal Gap: Martian megafloods in the Hesperian epoch occurred 3.0 to 3.4 billion years ago, while younger outflow channels like Athabasca Valles are estimated to be 2 to 30 million years old Verified Answer #3Verified Answer #6. Human language emerged only approximately 300,000 years ago, creating a multi-million-year gap where narrative preservation is statistically indistinguishable from random noise Verified Answer #2.
• Phylolinguistic Analysis: Computational analysis of global flood myths shows they are dominated by "terrestrial emergent tokens," such as local rivers and indigenous animals Verified Answer #1. These myths lack "anachronistic semantic tokens" describing Martian-specific features like low-gravity phenomena or non-Earth orbital mechanics Verified Answer #1.
