Possibility to find primitive lifeforms on our solar system

When we are researching the possibility to find alien life, we often forget to describe, what kind of alien life we are looking for? Are we looking for intelligent alien life or primitive alien creatures like bacteria or some kind of amoebas? If we are looking for the last ones, we must realize, that those creatures might live even in our solar system, and one of the most promising place to find those alien creatures might be the Europa-moon of Jupiter. There is a possibility to find the creatures, what are similar to organisms, what is found near "black smokers" or underwater geysers.

That kind of life forms could be very often, and some of them would not have internal mitochondria, and that means that they would need an external heat source for maintaining their life. Those creatures would not move far from the volcanic eruption holes. And if those creatures would go too cold their metabolism would be stopped, and that thing makes them hard to notice.

This kind of things means that only when we can send very sophisticated laboratory to some of the Jupiter moons, and then the submarine, what the lander would deliver on the surface of Europa to the under-ice mission would send the ample of bottom mud to that laboratory we would get an answer, what kind lifeforms there could be. The thing is that the ice core of the Europa is very unstable, and that's why the laboratory must build on some other moons like Ganymede or Callisto.

Europa and Io are very active moons, that earthquakes and volcanoes can risk the mission. Callisto is the geologically stable moon, which would offer a good place for surface laboratories. Those laboratories would send to those moons by using unmanned spacecraft, and the robots that are using artificial intelligence would build the structures. Before astronauts can send to those moons, the system must confirm, that is there some lifeforms on those moons, and is that lifeform dangerous.

There is a possibility that also Callisto has some kind of lifeforms in the holes of ice. Those creatures might look like some kind of alga or Diatoms, but the thing is that before this kind of thing is confirmed, we cannot be sure that the mission would be so safe as possible. The problem with those explorations is that they could take many years. And if some astronaut would pollute by the alien lifeform, that could be risk also on Earth.
