Extraterrestrial life

Hey everyone I was just thinking whether there are alien lifeforms on other planets because although I think that there are no aliens there might be aliens on other planets or even stars?Aliens might be there on mars because there is water on mars and there is an atmosphere.the aliens might breath in different gases for survival.Mainly I can say that there might be alien life anywhere and they might be more intelligent than us.In some cold planets they might use liquid hydrogen instead of water. If planet is well lit then i suggest aliens must have eyes. Maybe their body setting will be different than ours and perhaps they will be more
intelligent.Life is suggested to be there in mars ,jupiter's moon uroka and dwarf planet eris.But we dont know the limit there might be life beyond this.What do you think?

There has got to be life on other plants. If humans were created some how there is no way that we are the only life in the entire universe. Even bacteria is considered life, so therefore water may have bacteria in it like some of the waters on Earth. Life does exisit our society just has not discovered it yet.

There could be aliens in other galaxies but i agree with u there might be aliens on mars they could hiding from the rover because they might not wont to be seen by other aliens.

Mars is more or less dead by now, if life still exists there it will probably only be in bacteria form. it is believed that mars was once furtile and there might very well have been plant and animal life. but those days have been gone for a long time, mars is a good look at how our planet will look when it comes near the end of its life.
