Africa is not Europe...t?
That is where we are now. There are two type of Aliens on Earth - One type comes from reborn business where there are many who were somewhere else as the real Aliens. They come here and understand the nature of the planet, live among us and help to improve the planet slowly...that is going on now...like Einstein type of people.
The other type is direct Aliens...who already know who are their counter parts in the reborn sets. Therefore there are serious rules to access their technology directly now. In future, when we are somewhat close to it, the group will contact to their other side to make a go. That has been the case for millions of years...why change it now? Just think about Contact the movie...
In my engineering work, I could tell some of these people who have super high technology understanding that normal people would not have it....otherwise think about greedy people who will take the direct technology and make a mess of the planet in no time....so stick to the rules of the game...and we will see better in a few hundred years...as many are working globally....(you will see some of those, unless you are one of them...)
