Do you believe there has ever been life on Mars?

Answer 1

What, did everyone forget about those Martian meteorites found in Antarctica a few years ago? Not proof positive, but very compelling as bacteria fossils. And now the news about vast oceans covering the surface 2 billion years ago? I would definitely bet large amounts of $$$ that genuine life, of at least the protozoan level, existed there at one time, and perhaps still does. We'll know for sure in just a few more years once those polar excavators arrive.

Answer 2

Mars has been often referred to as Earth's fraternal twin. There have been possible traces of vegetation on the planet, though as that isn't for certain, there are traces of water. From what I've read, the planet was without a doubt a habitable planet at one point in time. Whether or not there were civilizations on Mars is up for discussion by anyone.

There's a lot of evidence supporting the fact that Mars may have had a magnetic force field, quite like the deteriorating one that Earth has today. It's a smaller planet, therefore if there was a civilization it could have adapted much faster than Earth. The magnetic force field on Mars possibly deteriorated for the same reason that ours currently is, once it did deteriorate, it would only make complete sense that asteroids and meteors did strike the planet, leading to the extinction of life, and the drying up of water.

Mars at the moment looks like a barren wasteland after the most cataclysmic of events. I really believe that it was once flourising with life.

Answer 3

Mars seems to have had a thick atmosphere and oceans for a good while. Life on Earth developed almost as soon as the planet had cooled enough for oceans to exist. So yeah, I find it very likely that there could have been some kind of life on Mars. No vanished civilizations or anything like that but simple life - certainly.

It's actually fairly important for the search for life elsewhere to know whether life existed on ancient Mars. If it did then it indicates that water + warmth = life, and those are conditions likely to be quite common in the cosmos. If it didn't then it means you can have a planet with perfect conditions for billions of years and life never developed, which indicates it may be a lower probability event than Earth history indicates.

Answer 4

I believe there was once life on Mars because smaller planets evolve faster, and die faster than larger ones and there is evidence of water once having existed on the planet, and, as everyone knows, there must be water to have life. When I'm in a mood like you're in I begin to believe that an advanced civilization on Mars escaped their dying planet and came to our Earth...so that means we are the Martians.

Answer 5

Sure there was long ago. I believe life ceased to exist on Mars about 160,000 years ago. There is evidence that there used to be water flowing on the surface, and we also found ruins. The government is not too sure how we are all going to handle this alien thing. The last thing they need is all 300 million of us freaking out at the same time.

Answer 6

This is not something we should ever put down to belief. We should only come to a conclusion either way for anything once we have obtained sufficient evidence to support it, and there is not sufficient evidence of life having been on Mars, nor of there never being life on Mars, to make that call.

Answer 7

Good chance that there once was some form of life.
Recent evidence suggests the Mars held significant water at one time.
Who knows what lies below the surface.

Answer 8

Well we have never discovered life on any planet except the planet earth. And for lack of any great evidence I would have to say no since I have no reason to believe that there has been any.

Answer 9

I would bet that there was bacterial life on Mars at one point. I doubt very much that there has ever been multi-cellular life there.

Answer 10

yes and one day the life of a diff planet will be examining earth and saying u know there used to be vast oceans on earth i wonder if there was ever life
