Hi @cianjw, I don’t know much about aliens! I know that so far there is no proof that any intelligent life exists in our solar system, but some scientists have sent out radio signals into our universe which could be picked up by other intelligent life (if there is any out there). Mathematicians have worked out that statistically it is likely that there is intelligent life like us out there somewhere, but it may take us thousands of years to find!
