Quads don't lie
Even if it were aliens, and that's a really big fucking if. By the time a message reached them hundreds of years would have passed.
Honestly i don't want to contact them, intelligent life as i know it has proved to be some greedy bitches who want everything. I don't want an alien invasion because they have spent their supply of resources, and will be looking at us like an amerifat looks at taco bell.
