  I wouldn’t rule out the possibility of multicellular life. In terms of the chances, this is where we turn to the Drake Equation. Now, the Drake Equation is very simple and the solution seeks the probable number of intelligent alien life forms in the Milky Way, and some of the variables in the equation are up for debate. But some individuals have used this equation to estimate that up to 72 intelligent alien civilizations could have spontaneously developed in our galaxy. Whether this is accurate and if we could ever contact them is another story.
