Sorry, but it seems like your argument is that more complexity = more
human-like, and that therefore more human-like life is more complex,
which is circular (and objections aside, is a version of the scala

Except that no such civilization is known to exist and there's no
compelling evidence that it ever will. On the other hand, there is
evidence to suggest that bacteria can be ejected from the earth by
impact events and lie dormant in space for a long time, potentially
seeding other planets. It's possible that single-celled life from
Earth has already accomplished this, no "complexity" required.
