No
Yes people believe that.
Well, Mars's conditions is almost like Earth's. Therefore people agree there was (or is) life on Mars. Wither that, or there are LUNATICS who make people gullible enough to believe in aliens ;)
No, but scientists believe that there could have once been life on Mars.
People may disagree with the idea of life on Mars due to lack of conclusive evidence or differing interpretations of existing data. Some may also believe that the harsh conditions on Mars make it unlikely for life to exist there. Additionally, skepticism is a common reaction to extraordinary claims, especially in the scientific community.
Some people believe there are aliens on Mars due to photos capturing mysterious shapes on the planet's surface or a desire to believe in extraterrestrial life. However, there is no concrete evidence to support this claim, and the scientific community has not found any conclusive proof of past or present alien presence on Mars.
yes
On mars it is hard to believe but there is a form of bacteria on planet Mars scientists are still trying to figure out if there might be other forms of life on Mars so in the 2018 scientist will send a spaceship there to see really close for et on Mars.
As yet we do not believe that any other planet can support life. However there is evidence to suggest mars once did.
I believe it is water and life.
NASA believes that there is in fact life on mars but they are not 100% sure. they do believe so. if you really want to find out go on Google.com and look up "NASA: life on mars" thank you for reading my answer.
There is currently no evidence to suggest that any form of life exists on Mars. However, scientists believe that Mars may have had conditions suitable for life in the past, and they continue to search for signs of microbial life on the planet.
Not having water on Mars is not something to overcome - unless you believe water is necessary to life and you are trying to figure out how there could be life on Mars. If that is the situiation, then you can only overcome it by seeing if there might have been water on Mars in the past.
