...away, millions of years later? Okay so I learned in class that the furthest thing we can see (with telescopes of course) is 14 billion light years away. But estimations of the age of the universe is 14 billions years... But, how does that work? Because 14 billion years ago our solar system would be right next to this object... (say the big bang just happened [this assumes that our solar system appeared at the start of the big bang... which I know it wouldn't have], but light doesn't get destroyed or wait around for us to start looking for it) so if the light already reached us 14 billion years ago, why are we seeing the same light from this object today?
 
light only travels so fast
when we see a distant galaxy, we see the galaxy as it appeared ages ago
this is because the light given off now has not yet reached us.

its like hearing an echo
it takes time for the sound waves to bounce off of whatever it is and return to your ear.
