True, but on the other hand humanity has been left alone for millions of years, so odds of some species conquering universe just after humans accidentally happen to meet them (while they are still very limited in size) seem low.
If there would be nothing stopping such expansions, i would´ve expected seeing some species conquering universe millions or billions of years ago.
