Its possible, if there really is a huminoid ancestor
that spread its genetic code all over the galaxy in hopes of creating beings like themselves...... but uh. i dont really believe that.
The universe is SOOOOOO big... SOOOOO BIG that its ridiculous to say that theres no intelligent life out there, and its SOO BIG that really anything is possible. I doubt that there will be anything that is a bipedal humanoid.
