There has to be, the numbers don't lie. Like said before, we are talking about billions of galaxy's and trillions of planets. Ever the smartest best sciences have trouble trying to wrap their minds around the numbers and distances, which are measured in light years, the speed of light traveling a year.
Another thing about the distances, the nearest star is 4.6 light years away while the farthest star is 13.2 billion light years from earth. When we are outside looking up at the stars we are looking at the PAST. The nearest star light we see happened 4.6 years ago, other star light happened millions and billions of years ago, we don't ever know if they are still out there. If a star is 10 million light years away and it blew up 5 million years ago we will not see it happen for another 5 million years.
Remember the movie, Contact? They got it right on one thing. Our radio and TV signals travel at the speed of light and ARE STILL TRAVELING away from Earth. The very first TV signal we sent out over the air was Hilter speaking in 1936. THAT is their first impression of us. What are they going to think?????
