Never seen that image before, that is quite scary really. When people state that there is no such thing as aliens really annoys me when you see visualisations such as this.
There's almost definitely aliens out there. The question is, will we ever get to meet them?
Of course we will, just will it be in the next 100 years, the next 1,000 or the next 10,000?
It could be more than 10+ million years from now.
By that time civilization on Earth would be indistinguishable from aliens from our 21st century perspective.
