It is true that some scientists believe complex life forms are rare or possibly nonexistent.
Why can\’t alien life forms just be something very simple? Perhaps an alien life form is as simple as bacteria, radiant fungi, or virii. There are many viruses and whatnot with origins scientists cannot explain.
Now, the fungus growing on the fated Mir space station may have been terrestial in origin, but it was of such a mutant form that it wasn\‘t really explainable how it got so extreme. In all probability, bacteria can probably exist elsewhere, it\’s just really hard to see something so small from so far away.
