Life's building block is not life. Those things are amino acids and other chemical compounds that the DNA and cells require for making their protein shells and other structures. They don’t mean life as we know it. 

There are possible life-building blocks on Saturn’s giant moon Titan. So, does that mean that there is life on that moon? A life-building block doesn’t necessarily mean that there are any kind of life forms. That means that there are chemical components required for the DNA molecule assembly process. So those building blocks are chemical compounds, not life in the form as we know it. Titan is too cold for similar active lifeforms that live on Earth. 

Chemical reactions on that moon are extremely slow. And an interesting question is this: are those chemical compounds formed on Titan, or are some kind of meteorites bringing them to that moon? The origin of those chemical compounds is also an interesting thing. 

We must realize one thing. Life can be far different from what we even expect. Another question is this: should we call the self-replicating molecules “life”?

That is one of the most interesting questions in the world of philosophy. The chemical compounds, like amino acids, are quite common things in the universe. And in the Kuiper Belt, in an absolutely freezing area, those chemical compounds can exist almost forever. The is a small possibility that some kind of cells or DNA, or RNA  can travel between stars and retain their ability to infect cells. In those cases, the cosmic ice bite will transport those cosmic viruses between the stars. At 0K, the chemical environment is very stable. 

The thing that determines if those kinds of molecules can remain in its form is the case that pushed it and the cosmic ice bite out from its solar system. The nova or supernova eruption causes a very high-level radiation burst. That can smash planets into pieces. But there is a small possibility that the DNA or RNA can keep its form during that radiation burst. So, can life travel between solar systems in the cosmic ice bite? That kind of ice bite is not yet found.
