I thinkw e closed that one ages ago with the conclusions that
A) "Life" doesn't equal little greeen men but can be a 1 micro meter blob of green goo.
B) Life will be very common in the universe
C) How common intelligent life is is anybodys guess
D) How common humanoid type life is is anybodys guess

We just don't know how much advantage humanoid type life gives to a species... and we really need to if we are to make any resonable assumptions on its rarity/commonness
