But on a serious note, there are many scientists and I do not know all of them, there are too many to name. It is not just one scientist and many do. Also it is not simply claiming the "is" life, but seeing if there is. Nobody knows for sure, we just want to know and see if there is.
No life has been found on Mars as of yet - and no intelligent life exists there. As such, there are no alien houses on Mars.
Because Mars is near the habitable zone of life for a star system, it has an atmosphere, and it has water on it, and water is essential to life.
Scientist believe that the planet Mars used to have flowing liquid water. Now, the water on Mars exists almost exclusively as ice.
Scientist have found what looks to be a place were there was once water so there is a big possibility.
Scientist believe there can be life on Mars, its atmosphere is similar to ours they say but right now their studying it.

This question is remains unanswered. There is evidence of frozen water, small oxygen levels and some prehistoric fossils. This piece of evidence concludes that there was life on Mars. Obviously scientists will need more evidence before they are able to decide on if Mars has life.
They found water there.
Currently there is no evidence that life exists or ever existed on mars, so it is unknown
scientist are looking into it, but there is no definite news that there is a core. If there is no core that explains why there is no life on mars and humans can also not live on mars then.
to see if life is living up there
I'm no scientist, but I'm going to have to say, no. If there was snowfall on Mars, there would probably be life on Mars. Where there is water, there is life. No, I'm pretty sure, almost positive, there is no snowfall on Mars.
Because Mars is near the habitable zone of life for a star system, it has an atmosphere, and it has water on it, and water is essential to life.
Many instances of martians have been written about, but to date there is no real evidence that life of Mars actually exists. Many people claim to have been abducted and these references are in books and online.
There might be, though scientist haven't figured out yet.

No scientist has ever been to Mars.
