The furthest any signal from earth has gotten is 100 light years. Don't forget that signals degrade also, so even if someone were to receive a signal 100 light years away from Earth, it might well be indecipherable or indistinguishable from background noise of the universe.
Voyager 1 isn't even 1 light year away. It took 35 years just to leave our solar system.
Our galaxy is about 90-100 thousand light years across. The Universe is like 92 billion light years across. The entirety of possible human influence on the universe is like 1/460000000 of the universe.
Is there other life in the universe? Absolutely. Is there, has there, or will there be other intelligent life in the universe? I can't fathom how their couldn't be with the universe being as vast as it is. Does anything else know about us? I don't see how.
Some other intelligent life would not only need to be currently advanced enough to discover us, but they'd have to be looking for us, and they'd have to know exactly where to look to even have a chance of discovering us. If something were to discover voyager, they would have most likely already discovered us on Earth (you know, since they'd have to be damn near next door).
Think of it like this. Take 3 olympic sized swimming pools and stick them together. Earth is a single drop of water in that pool. You can only detect that single drop of water if you are actively looking for it and within 4 inches of it. That would represent just our galaxy. You would need 1 million swimming pools to represent the universe. As you can see, the chances of anything else in the universe even being aware of us is unfathomably small.
