My opinion is that nothing flies there... It's unlikely that anyone has seen any alien spacecraft. Of course, I'm not denying that there are intelligent beings and civilizations somewhere else; the universe is vast, and there are bound to be other intelligent beings like us. But I don't think they've reached us yet. Of course, anything is possible. But it seems to me that they can't live on the planets of the Solar System because we would have already noticed them. And if they live somewhere near Antares, it's interesting how long it will take them to reach us.
