What if they don't want to be noticed? The way you say it, it sounds like the aliens travelled so far with the intention of making contact with us. What if they are just passing by? Also, the problem I have with time travel is in order for it to happen, everything in existance except the one travelling through time would have to be reverted back to its original state. Even if this could be achieved, then how could the future from which one originated still exist? Would the time traveller be trapped in the past? To me, time doesn't really seem to be something that can be manipulated. But this is just my opinion.
PS: spikeman25, if you look at my reply, you can see I pwned Stellar back.
If we were the ones who could travel light years away and chance upon an extraterrestrial civilization, wouldnt we present ourselves to them and not hide? So it makes more sense to think if they ever came here they would have contacted us. About time, theres no proof of this but what if we can divide time into segments, each day is a segment so if you go back a day you see yourself going through the routine you went about yesterday and you see yourself aday younger. If your 30 years old and travel out 30 light years away to a distant star, when you reach there you'd still be 30 years old essentially but everything back on earth would be 60 by then. So I feel its possible to manipulate time its just that we havent been able to find out how.
