When it comes to technological development or advancement, the invention of satellite is the climax of intelligence gathering because with the use of satellite technology, the world is fully equipped to run all manner of surveillance system software that is capable of protecting and helping the world fight whatever opposition that might come up in the future whether it's human threat or alien threat.


Take it or leave it, aliens do very well exist and it's with the use of satellite positioned in the outer space of the world planet that man get to use and monitor whatever happens.
The world's technology would never be the same without the invention of satellite technology. All the advancements in all the human fields would never be possible without the satellite.
