It always surprises me when scientists think like this. They are trying to take our current technological levels and extrapolate out from there.
It's most certainly reasonable that there are literally a couple billion intelligent life forms - many former residents of Earth who have passed to a different plane of existence - who have ability to observe the behavior and actions of our current human population.
I concur there's little doubt that most would be amused, much as we find amusement watching a young child stumbling and plodding their way through life.
Check this out. The Hubble Deep Field.
It's actually hard to comprehend big the universe is.
Pretty amazing.

Speed of Light = 12000 Lunar Orbits / Earth Day
But 1400 years ago it was stated in the Quran (Koran, the book of Islam) that angels travel in one day the same distance that the moon travels in 1000 lunar years, that is, 12000 Lunar Orbits / Earth Day. Outside the gravitational field of the sun 12000 Lunar Orbits / Earth Dayturned out to be the local speed of light!!!
This definition is independent of direction and common to all observers: An observer near a black hole, for example, sees the speed of light outside gravitational fields a zillion km/s but still equal to 12000 Lunar Orbits / Earth Day!!! Learn more http://www.speed-light.info/
