For years, astrobiologists have debated the source of fluctuating methane levels detected in the Martian atmosphere. Some researchers argue that these seasonal variations are biogenic, suggesting that subsurface microbial life releases methane during warmer periods when metabolic activity peaks. This biological explanation is supported by the rapid fluctuations observed, which are difficult to model using slow geological processes alone.
Text 2
While biogenic methane is a compelling hypothesis, abiotic explanations for the Martian atmospheric fluctuations remain highly plausible. Ultraviolet radiation striking meteoritic organic matter on the Martian surface is known to release methane at rates that increase with solar intensity. Furthermore, chemical reactions between water and minerals, such as serpentinization, can produce seasonal methane spikes when subsurface ice melts and reacts with surrounding rocks.
Based on the passages, is the statement that the author of Text 2 would characterize the biological explanation in Text 1 as insufficient to rule out geological or chemical alternatives true or false?
