Hell, we'd be "lucky" to find anything that's multicellular, or even similar to our eukaryotes. "Life" on this planet has been (and still is) primarily simple prokaryotes, with horizontal gene transfer, no sex, very small size, very small genome, low energy production, etc.
First couple billion years was all that, and they still are the vast majority of organisms. And eukaryotes seem to have evolved (only once!) pretty much by chance and not by necessity.
Chances are the galaxy is teaming with that kind of thing, but what we get excited about as "life" (stuff like us) is exceedingly rare, and there's no reason to assume that next-level "complex" life will exist in a form we even recognize, if it exists at all.
