Most probably microbial with a rare sprinkling of intelligence equal to or superior to man. Why haven't we been contacted? A guess is the intelligent beings, while rare, are separated from earth and each other by tens of thousands or more of light years. If so, there is little to no chance of contact directly or accidently becuse of the overwhelming distances involved. Radio frequency transmissions degrade to nothing detectable against the background of natural cosmic electromagnetic noise in just a light year or so depending on the original power level of the signal. Sublight speed space travel over the same tens of thousands or more of light years separation makes no sense no matter how it is viewed. If this conjecture is anywhere near accurate, mankind or any other intelligent life form will never ever meet their cosmic neighbors.
