In 1996, NASA scientists claimed that a Martian meteor contained chemical compounds that indicated life...

**Identify the contradiction:** NASA scientists found chemical compounds in a Martian meteor that suggested the possibility of ancient life on Mars. However, similar compounds were also found in Moon rocks, where life is not believed to have existed. - **Analyze the evidence:** The presence of these compounds on both Mars and the Moon suggests that these compounds are not unique indicators of life. - **Scientific approach:** To resolve the contradiction, scientists must consider the broader context and properties of these compounds. The appropriate response is to recognize that the compounds alone do not provide conclusive evidence of life. This requires a cautious interpretation of the findings and a search for additional, more definitive indicators of life. - **Conclusion:** The correct approach is to understand that these chemical compounds do not necessarily indicate life, as their presence can be attributed to non-biological processes as well. **References:** Integrated Physical Sciences textbooks, scientific journals on astrobiology, and NASA reports on Martian and lunar geology.
