I don't get why people generally presume intelligent life from another planet is so advanced.
It most likely will not be so advanced that they can do all the things science fiction says.
Most likely only space travel and sustaining life in closed environments for long periods of time.
There certainly IS life elsewhere in this universe, but we can't even begin to know what to expect of it.
If we find a planet that has its own intelligent life and they, too, wonder if they are alone or not, it may not turn out all that well. (Testing on each other, hmm?)
EDIT:
All UFO sightings ever have been on certain lines of latitude, and on these same lines of latitude are some sort of ancient ruins.
On every

Stonehenge.
Between Stonehenge and some place in France, there are 35 bloody towns with the root word "star".
EDIT 2:
All religions seem to revolve around someone coming out of the sky and making everything.
Ancient religions depict ROCKETS in their cave drawings.
All religions can easily point to life on other planets coming to Earth. :O
