I don’t think for any second that aliens will arrive soon here on Earth. They aren’t interested. They are laughing at us, because we’re the only ones searching and waiting for their arrival. I know there are programs saying that anytime soon we are going to encounter them. The possibility of that happening is 5%. We won’t be able to befriend them, or fight against them. I don’t waste precious time waiting for their arrival. It is never going to happen soon. Yes, they do exists. But, this is the reality we are facing. I think we shouldn’t waste our time on it. There are other things to do, think, and talk about. They are in other galaxies and universes we can’t go to, because if we do we will die in space. This is most likely. The miles to travel to find life is that you will reach a hundreds of years old, unless we are able to create wormholes and travel through them. You will never come back to Earth. The best thing we can do is to have discussions about aliens, and their advanced technologies. I know there are machines built here for them to come, but they will be disappointed when they don’t. So, the best scenario is to leave it alone, which I think some experts won’t do it.
