The planets are being drawn toward the sun, as the planet draws nearer, the environment starts to dissintigrate as the ozone layer is destroyed and all life slowly killed off.. the key element of life, liquid water evaporates and only the extreme depths of each pole continue to contain what little frozen water remains, until it too evaporates and the planet Mars effectively dies forever. Eventually it will be consumed by the sun and the sun will grow as it has for billions of years, at first sustaining life, then swallowing it into its own form and source of life.
Earth too will eventually meet this fate, and humans will possibly need to jump from moon to moon seeking survival?
Is this plausible considering extreme hypotyhesis?
I learnt today they finally found proof ice exists on mars and water once flowed plenty.. but when? Was it before Earth fostered life? Did life once only exist on Mars then and has now skipped to Earth, slowly evolving;only to be extincted like Mars.

You're assuming that the orbits of the planets are much more unstable than they actually are. The orbits of the planets are indeed becoming smaller, but at a rate almost too small to measure. Long before any planet swoops in close enough to the sun for what you're describing to happen, the sun will have already moved off the main sequence, become a red giant, and wiped out any and all life on the terrestrial planets like Earth and Mars.
You're not confusing the annual approach towards and away from the sun are you? The planets' orbits are all ellipses, not perfect circles, so they move in towards the sun and then away as they orbit it.

There is plenty of evidence for water and dense atmosphere in the history of Mars. The glass tunnels. Those are a curious thing which need looking at closer. Its a bit early to say some sort of intelligence made those.
Your science is way off on the atmosphere. The core of Mars froze and the magnetic field died with it. So without protection the the solar wind could blow away the atmosphere.
The planets are being pulled into the sun but the rotational force is balancing this out so the planets are not moving nearer or further away.
The sun is indeed set to expand until it eats the Earth, then will shrink into a white dwarf.

If Mars was being drawn closer to sun, it must have been further off and as it goes away from the sun, the temperature drops drastically and so, water would have been ice, not water and so the question of boiling off doesn't arise. However, since Mars has lesser gravity than earth, its atmosphere would have been lost slowly over ages and that would have also removed most of the surface water due to evaporation at the equatorial region and confined it to the Martian polar region.
The sun is going through a steady state now and after the hydrogen is consumed, may start swelling up and become a Red Giant or collpase into a dwarf depending on the balance between the expansive forces of the gases and the gravitational pull due to the mass. If Sun expands into a Red Giant, life on earth may die off because of the increased heat.
So, I would request you to rework your theory.

That doesn't really work though, because Mars is farther from the Sun that Earth is. For that theory to work, the heat or solar energy or whatever from the Sun would have had to kill off (or push away) the Martians before Earthlings existed, which would mean that Mars would have to be closer to the Sun. However, if Martians were much more sensitive to the Sun's rays than humans and other animals, I suppose it's somewhat plausible, but that would have to be a pretty severe sensitivity. Or perhaps Mars' atmosphere was already much weaker than the Earth's.
Regarding the planets being drawn toward the Sun, I believe that stars get bigger before they implode or become a black hole or whatever, and as they get bigger, their gravitational pull would likely grow stronger as well, so what you say could be feasible, on a galactically tiny scale. I think.

The planets are not moving toward the sun at an appreciable rate and the sun is not expanding. Yes, eventually the sun will get to a red giant stage and swallow the earth, but most of your "facts" are not correct. Try a new line of thought.

Mars replaced into practice diverse than earth. particular mars had water and a environment once upon a time. It nevertheless does water ice on the poles and below floor. the ambience it skinny. we are able to work out that with the mars rovers and the satellites orbiting the planet. the priority i imagine is Mars center began to harden way previous to earth and it does no longer have the nuclear reaction that earth does on the middle. So, Mars lost its Gravitational field and the photograph voltaic flares from the solar stripped the ambience away killing the planet. I shouldn't say kill, it o.k. might want to even at present help small forms of existence. we are able to ought to bypass there to substantiate that. The Volcano performed a roll on Mars, in spite of the undeniable fact that it did not make contributions to the shortcoming of life of the planet.

we have to wait and see, researches are going on, we may get a perfect answer in another one or two years.
