The nearest star is only 4 light years away.
Radio and tv transmissions travel at the speed of light.
So far from not receiving any transmissions they’ll have watched all City’s success up to 2019.
There are over 10,000 stars within 100 light years never mind 200. They will have been receiving radio signals for 100 years and will shortly start receiving tv signals.
I'm hoping that when they receive those early tv signals they'll remember to tape all the missing Doctor Who episodes as that would fill the gaps in my collection!
On a more serious note it seems more probable than not that the universe is teeming with life. The search for extra solar planets identifies more and more, including life friendly ones. Hydrogen appears to be the most common element in the universe, no reason why oxygen isn't as available, therefore the is likely to be water in some form out there.
Carbon would also be common according to mass spectrometry and if you put those three elements together, under the right conditions, proteins form, that can lead to amino acids.....
So there is likely to be life out there, but is it like us, or primitive, like bacteria or Martin Keown!?! Other star systems may have formed much earlier than our Solar System, perhaps lifeforms evolved formed civilizations, created technology. If so it could be at least thousands of years in advance of ours.
Space is very big, the distance and time to travel to our nearest star systems would be hundreds of years. However for a hi tec civilization with technology far in advance of ours, coming to Earth, might be much easier. Hopefully they'll be benevolent like ET, rather than say Independence Day.
However human history teaches us that whenever one technologically superior civilization encounters a less advanced one, there is usually not a good outcome for the indigenous people........
There are other places in the Solar System to explore, hopefully we can become an interstellar species, and expand our habitats.
