Astronomers are now certain that Mars had water - probably a great deal of water - at one time (it still does as ice in it's polar cap), and also had an atmosphere at one time (now, just a very, very thin CO2 atmosphere). The combination of the two, with lightning from atmospheric storms mixed in, are the basic ingredients for the most elemental life forms to begin developing. Bottom line? Mars may have had life at one time.
What else can I help you with?
Why do these regions lead scientists to hypothesize that there may have once been life on mars?
Regions on Mars that show evidence of past water flow, organic molecules, and potential sources of energy, such as methane, lead scientists to hypothesize that life could have existed on the planet. These conditions resemble those necessary for life on Earth, suggesting that Mars may have once been habitable.
Do all scientists agree that the meteorite from Mars shows that life once existed on Mars?
No, not all scientists agree that the meteorite from Mars shows evidence of past life on Mars. There is still ongoing debate and investigation regarding the findings and interpretations of the meteorite known as ALH84001. Some scientists argue that the evidence may be the result of abiotic processes rather than biological activity.
What planet do scientists believe life may once have existed on?
mars. now tell me why they think that?
Who vanished life on Mars?
It is not known who vanished life on Mars. There are however proofs that there was once life on Mars.
Do Mars have creature?
There is no scientific evidence to suggest that there are currently any creatures living on Mars. However, some scientists believe that microbial life may have once existed on the planet in the past. Ongoing missions to Mars are actively searching for signs of past or present life.
Why do scientists hypothesize that mars may once have the conditions needed for life to exist?
Since life as we know it requires water, scienctists hypothesize that Mars may have once had the conditions needed for life to exist.

Scientists hypothesize that life may have existed once on what planets?
Yes, demonstrably the planet Earth has life. Scientists are currently looking for life on Mars (no proof of life recognized there yet) and are speculation that some extrasolar planets may be in the Goldilocks zone for life.
Is living thing is possible in Mars?
No, but scientists believe that there could have once been life on Mars.
Why do scientist hypothesize that Mars may once have had the conditions needed for life to exist?
life to exist there

What planet do scientists believe life may once have existed on?
mars. now tell me why they think that?
Are there any life form on mars?
None that is known. It has been suggested that there may once of been life on Mars, but most scientists think it is unlikely that there is any life there now.
Once these rocks are observed by scientists, do you think we will have more answers to the question of whether or not life was once on Mars?
yes I think they will
Could you send up insects to live on Mars for a test?
Once scientists are certain that there is no native life on Mars, then sending microorganisms will probably be the first lifeforms we send there.
Why do scientists believe life may have existed on Mars?
We have found minerals and other formations on Mars that show it once had bodies of liquid water. As we currently understand it, liquid water is the most important ingredient for life.
Who vanished life on Mars?
It is not known who vanished life on Mars. There are however proofs that there was once life on Mars.
