24. Another theory allowing life on Mars is the possibility of Earthlike conditions in the past.

25. Scientists have discovered signs of flowing surface water, but Mars could have been even more Earth-like at one time.

26. A change could have occurred as CO2 became trapped in rocks.

27. Since Mars lacks the tectonic and volcanic activity that cycles CO2 in the Earth¡¯s atmosphere, the atmosphere could have been depleted of gaseous CO2, over time, which would have reduced the greenhouse effect and destabilized the atmosphere, allowing most of it to dissipate over time.

28. This could have allowed a gradual disappearance of water from Mars¡¯ surface or its absorption below Mars¡¯ crust, where it may still exist, until life became unsustainable.
