question 1
Mathane is a type of gas. it is composed of four atoms of hydrogen bound to one carbon atom. it is the main part of natural gas on earth.
question 2
scientists think that it is evidence of life because living organisms create methane.
qustion 3
i dont think that this is proof that there is life on mars because methane could possibly be created in other ways that people on earth haven't discovered.

1.What is methane?
- Methane is a gas that is quickly destroyed in the martian atmosphere.
2.Why do scientists think it is evidence of life?
-That there has to be a reason why the gas keeps coming back and then going away. then coming back again.
3.Do you think that this proves life on Mars? Explain
-I don't think it proves that there is life on mars, i think the only way to FULLY prove that there is life on mars, is by actually seeing that life.
