This golden record will likely never be found. But let’s say that billions of years from now some Jedi master comes across it in a galaxy far, far away. Is this going to make any sense? If an alien civilization is technologically advances enough to pick it up in space, yes, it should make sense. And if it decides that the Earth is ripe for conquest, fine. It’s not going to be the Earth displayed on this disc.
Because the disc doesn’t show how dangerous we can be. All the alien sees is a lot of little kids, and a lot of people eating. Really, what kind of fight are they going to put up. In the next mission, send out a copy of the movie “Independence Day,” even with all its flaws. That will take Earth off the alien visitation list.
