From so far what we know from NASA explorations, no. But among other planets, conditions on Mars are most similar to that of earth (no liquid water, but ice) so we can always be hopeful 🙂

No one knows.
But we know that there were once rivers, lakes and even seas on Mars. So maybe life existed there in the past, and maybe it even exists there now in the form of microbes or other microscopic life.
That’s why we keep sending spacecraft to Mars to get evidence of where life might have existed.
The next two rovers will go there in the years 2018 and 2020, and they will look for signs of life in the past, and whether there is life there now.

We don’t know, it is one of the great unsolved mysteries at the moment! At the moment we haven’t found evidence for life, but it can be hard to do experiments on other planets so we haven’t done all the searches we would like to do. We think that the conditions for once right for life on Mars so there is certainly a chance that life once existed on Mars, and it might still exist hidden away perhaps under the surface or under Mars’ frozen ice caps. Hopefully one day soon we will be able to answer this question fully. It will certainly be a very exciting moment if we were to find life on another planet!

We don’t know – maybe! It might also be that there was life on Mars in the past but not anymore. I think this is one of the most exciting open questions in science 🙂

Not from what we’ve seen so far! If we do find anything though it would more than likely be similar to a single celled organism rather than a green alien!
