Implications of Life
Scientific Research and Design
In the meteorite Allan Hills 84001, scientists found structures that they believed could be fossils of ancient microorganisms as well as organic compounds. Now that result appears inconclusive, or possibly false, because the same hydrocarbon evidence can be produced by abiotic processes (Golden et al., 2000). It is even possible that that terrestrial bacteria have contaminated the meteorite, making any confident statement about extra-terrestrial life questionable (Steele et al., 2000). However it must reiterated that the possibility that the rock contains fossils has not been eliminated. The possibility of life on Mars will not be ruled out even if this meteorite is proven to not have life.
