Well I live in Israel and about 3 months ago I was in the dead sea with my friends .. I looked at the dead sea and I was amazed that there is no life in the hole big location of the dead sea, something that is abnormal here in this world.. The dead sea is a big space that contain no life even in the desert there are no such big places that contain zero life...
And it made me a bit sad because i know the latest news from mars orbiters and rovers and landers are that mars was and is a very salty place and if there were liquid water on mars they were full with salt..
But then I looked at the left of me and what I sow?
I sow a string of water that came from the showers and next to this string of water there were planets growing... and then it hit me of course the landers and rover's will not find anything... This is because all the time they were searching in leveled places in the button of mars lakes and seas that contained no life of course because it was all salt.. If there were life there were on the strings that spilled into the large salt seas, If we want to find evidence of life the landers should be sent to the mountains to the strings of the mountains.
I have some pictures...



This is the plants that grow on the string of water.



What do you think?

. . . Isn't Water [itself] a form of life [in itself] ?

I think, no it is not.

H2O. Not an amino acid. Not a protein. Not life.

The definition of life can vary...
My definition of life is a process that oppose the natural tendency of molecules to expand...
The thing is life is that it sort the atoms in a orginazied matter..
When there is no life atoms are spread across ...
When atoms are not spread widely with no repeated pattern there is life... When there is a process that make atoms organizes in the same repeated pattern it is life...


Sorry for my bad English.

Nope.
There definitely is life in the "Dead" Sea. Some microbes and bacteria can live there pretty much OK....just not animal organisms.

I believe the Dead Sea has a higher salinity than Martian soil, though I may be wrong about that. Anyway, we're only looking for microbes on Mars to begin with.

If there were life there were on the strings that spilled into the large salt seas, If we want to find evidence of life the landers should be sent to the mountains to the strings of the mountains.


Here's why that can't be true.
I see what you're saying about salt levels in ancient Martian lakes/oceans possibly preventing life. You might be right about that. It could very well be the case that life never developed there due to high salinity.

However, if life didn't develop there then it *definitely* didn't develop anywhere on the surface, especially on mountains.

The reason is that life on Mars could ONLY have developed either underground or deep within bodies of water as was the case on Earth. The Martian surface has never been protected from solar and cosmic radiation which would not only be lethal to any living organism but prevent the development of something as complex as dna to begin with.

This was the case on Earth as well when life originally developed. Earth's surface was bombarded by the cosmic and solar radiation from space, and no life could survive or develop in the first place. The only place life could exist at all was in our planet's oceans or underground, where they would be shielded from radiation by layers of water or silicate rock.

For a few billion years, there were living microbes thriving in Earth's oceans, but the surface was a rocky and barren wasteland, not unlike Mars is today. It wasn't until the levels of Oxygen (a waste product of the microbes) in Earth's atmosphere built up (after about 2-3 billion years) to the point where a thick atmosphere with an ozone layer came about; this protected the surface from radiation and life could finally migrate and thrive there.

We know that this build up of free oxygen in the atmosphere never occurred on Mars because
- There is no free oxygen on Mars today.
- Mars has a razor thin atmosphere and no ozone layer.
- According to physics, Mars was too small (and thus had too little gravity) to retain a large atmosphere; over hundreds of millions (or billions) of years, whatever original atmosphere it had was blown away by solar radiation; its oceans evaporated and/or were frozen into concentrations at or beneath the surface.

If microbial life ever evolved on Mars in the first place (which seems VERY possible given the fact that early Mars and early Earth were extremely similar), it would never have had a chance to leave the oceans or its subterranean home. Therefore, it could either be
- Completely extinct, but evidence of its past existence still visible
- Still alive, frozen in water ice just below the surface
- Still alive, living in active microbial colonies deep underground

. . . Isn't Water [itself] a form of life [in itself]?

Water as you know it is nothing more than the liquid form of H2O. It is no more alive than the layers of liquid metal hydrogen within Jupiter or the deposits of liquid methane on the surface of Titan.
