WHY does the vastness of our universe make it extremely unlikely that any alien race would have come in contact with us?
you just rearranged my words and muttered "nah."

I see what you're saying but it all depends on exactly
how frequent intelligent life is and whether they are alive in human's existance. There are so many varibles to aliens actually visiting us that it is actually extremely unlikely - think about it: first of all there has to actually be other life (almost definate), secondly that life must become intelligent (again, almost definately out there), thirdly that intelligent life must become an advanced space-faring species
during human existance. That's where it becomes less likely. Fourthly that intelligent, space-faring life must choose to visit us during human existance. That is extremely unlikely considering the amount of other planets. Assuming this space-faring species can travel across the galaxy, that is hundreds of billions of planets they could visit before they come to us. And all of that must be
within human existance, which is relatively an extremely small window.
Now all of that depends on the frequency of life, which we do not have a clue about. If life is very frequent (i.e. life in every other solar system) then yes, it is likely we have been or will be visited by aliens. If it is very infrequent (i.e. a few in every galaxy) then it is unlikely.
What I'm saying is that the vastness of the universe means that the frequency of life becomes the biggest factor is our likeliness to have been visited, and we don't know that.
Also, I'm not saying it is a
good argument, just saying that it is sometimes used as a point against this theory.
