Just read a news article about how 3 completely new types of bacteria have been found on the international space station due to it’s isolation, if that’s the case then how did they get there if we have never observed them before? what created them?

To add to the other responses, also note that such simple organisms can evolve very fast due to short generations.
I.e. while a generation for humans is in the ballpark of about 20 years, for bacteria it’s a matter of hours.
And while asexual reproduction does hinder the evolution, if you start with one bacteria and end up with a couple trillion in a matter of months, there ought to be completely new species evolved to survive in the new environment.
The same would happen to any other species, it would just take a lot longer, especially if it’s not artificially tweaked (like when humans bred new dogs for example).
