Well, what if consciousness is all linked, or we eminate telepathically or the Earth does, then maybe aliens are just able to sense us here because their ESP/psychic knowledge of the universe is developed to a very high degree.
On Earth we have life forms that are receptive/perceptive to all kinds of things humans cannot sense, why couldn't that be the case with other life forms. Like Donald Rumsfeld said:
"There are known knowns. These are things we know that we know. There are known unknowns. That is to say, there are things that we know we don't know. But there are also unknown unknowns. There are things we don't know we don't know."
Well this is my point!
Why and What?
Why would they send a ship here and what do they hope to gain from it. Maybe we are stronger than them with nuclear weapons. So they sent a ship with all kinds of tech gadgets to allow it to be seen and captured for the purpose that we lack the wisdom to use it. In which case it would destroy us. Maybe they do not want this planet or us but did it to amuse themselves. Sure we can relate to that as many members here start arguments for that purpose.
Who knows? Truth is often stranger than fiction.
Strange, but true.
Well people like to talk about Event A. I like to talk how did it happen and are we responding to it just as they thought we would not consider the event as a whole before it even started.
I have to wonder did this start at the time when we had our first radio broadcast and they(it aliens exist) received it.
