There's this book series that questions the impact of life on the universe. In the book they discover that life is very very prominent in the universe, and with that in mind, people began to question how much of the universe is natural. And how much of it is now artificial. it takes 4 years to send a message to the closest star system at the speed of light,  and that's if the message reaches in tact and doesnt hit a big field of debris. communication at our techological level is genuinely impossible, we are a blank spot in space that no other intelligent species can recognize as intelligent because we havent created a system that CAN communicate at these distances.  simply put we need to progress more so that we can join the community, or at least be aware of it. there's plenty of odd things in space we consider a natural phenomenon, but if we throw life in, especially intelligent life, a civilization that has been around for even a million years....well if god made the earth in 7 days, he might be a little slow compared to a kardashev stage 3 civilization.
