In this Galaxy? No. Elsewhere in this Universe? Extremely likely. Intelligent life forms? Reasonably likely.
Depending on what you believe, there is a theory that thousands of years ago extraterestrial life forms arrived on Earth and created "us" by cross breeding/genetically modifying out primeape states with their own knowlegde/genes to make the humans that we are now. This explains the so-called "missing link" in our evolution as the gap is between getting to where we are now from our more primative form. This is apparantly depicted on some aincient tablets somewhere which were created around this time.







So I'm guessing there is smething out there, somewhere.
