Let’s assume that there is intelligent life elsewhere in the universe, far far more intelligent than us – is it a question IF or WHEN will they visit us? I know that one could say "Well, the universe is so vast that the chances of them visiting this one planet in our one solar system is very improbable", but what if they too are looking for planets capable of life, and with their assumed advanced technology, planet Earth came up on their radar? Will they act like foreigners passing through Los Angeles and skip the small uncivilized "ghetto" planets?
