Here's a question for you: if intelligent life roughly fitting the parameters, capabilities, resources, and interests of human beings was at all common in the universe, how come we've never seen any evidence of it? Likewise with FTL travel. If it's possible to travel faster-than-light and it requires a level of technology that we can conceive (meaning alien civilizations capable of it should be ubiquitous), we should be getting visitors all the time, or at least detecting some really odd (inexplicable) characteristics in space where there's any FTL going on.
If I did not know better, I would assume you were one of those people completely clueless about how big the universe really is. Hell, just on our tiny planet how long did Native Americans go before they saw any evidence of other people from other continents? Some time. When we multiply that scale by a nearly unfathomable number and couple that with the fact that we have only taken one or two figurative steps into space, the answer to your question is rather obvious.
