if there was water and life on mars where are the skeleton remains? we got loads on earth like dinosaurs. also did mars have human life? in fact how did mars become so dead? did it move position from the sun?

there has never been human life on mars.
not all life forms leave skeletons.
who says mars is dead? it may only just be coming to life.
all planets are moving all the time.

Scientists are rather sure that at some point Mars had a rather good atmosphere, though not high in oxygen they think it was a heavily carbon dioxide and nitrogen atmosphere that had temperatures comparable to our arctic. At some point more recently it's core cooled, or some collision or event occured that froze the atmosphere, it crashed to the planet as a solid, leaving only the basic elements of an atmosphere that remain at that temperature. So far we only have a few probes that have landed on mars and they havn't found much. If there was life long enough to evolve we might get some solid remains but they may well have to be dug for which the probes can't do.

The remais NASA seeks are in the form of microoorganism fossils, very hard to locate with the ratio of their size to the planet surface and even below the surface. Their best bet is to decide where evidence leads them to believe water once was and search there. The colder mean temperature of Mars is far below that of Earth and if life ever existed there, it would be much different than any that ever lived on earth except for that which lives(d) in our most extreme regions. There are those who believe outside of the supernatural spontaneous creation of life, that another celestial body like a comet or asteroid may have deposited the protiens which eventually led to every living thing on Earth and those same elements may be on Mars but in the different habitat did not generate into more advanced life forms.

One theory is that Mars started to have life (microscopic) but the Martian atmosphere went away, and with it life. There would be skeletons (of a microscopic type) there now. Remember we can 'dig' for bones on Earth, whereas on Mars we have to look on the surface. If you shovel in 1000 places on Earth, what are the chances you'll find a dinosaur bone? Pretty slim I think

Most of the skeletal remains of past life on earth have been dug up.
So far, even with the rovers, we haven't been able to do much digging on Mars. It's unlikely that anyone will find skeletal remains there until humans with shovels arrive.
The climate on Mars is very harsh, the atmosphere very thin and it's unlikely that if there was (or is) life on Mars it would have been able to evolve into complex multi-celled creatures.
However, there are harsh environments on earth that support simple forms of life. So it's possible that Mars has similar organisms. To find them, human visitors would probably need microscopes in addition to shovels.
Whenever they go there, I suspect they'll take both.

The life we're looking for on Mars was probably microscopic. It is not a point of finding life that we can bring back to Earth and use, but rather to develop a better definition of what conditions are necessary for life to exist. If we can find reliable evidence for life on Mars, it also bodes well for there being life in other solar systems.

If there was life, that doesn't necessarily mean vertebrate life. It could be nothing more than microbes. Moreover, it's not like we've done excavations on Mars.
As to how Mars might have changed over time, that's one of the questions scientists hope to answer with further research. Remember, we're just now starting to scratch the surface, both literally and figuratively, in planetary research.

We do not yet know there was life on Mars, we only suspect. Finding fossils would change that, but when was the last time you found a fossil on Earth yourself? It isn't so easy, and you KNOW there are some. So it will not be so easy to find them on Mars, if they are there, since we don't even know for sure that they ARE there, much less where to look for them.

If there ever was life on Mars, it was no more advanced than bacteria, so you would never find skeletal remains.
Mars once had a thick atmosphere, but when the interior of Mars solidified, the volcanoes stopped, so there were no more gasses being added to the atmosphere. And Mars is small, so it wasn't able to gravitationally hold on to its atmosphere very well, so it lost most of it.

There is evidence of water ice under the martian soil, but so far there has been nothing to indicate the presence of life. If there were life on mars, it would most likely be bacterial in nature.

Untill people go there and look, we won't find anything. Fossil remains would probably be burried by the sandstorms that are common on Mars.
As for why Mars died, nobody really knows.
P.S. Mars never had human life.
