Do not really know the truth, but obviously I do not believe in any aliens. I think aliens are just imagination, or aliens are still speculation
The mysteries that have been there. Could have news aliens there are aliens in the form of UFO photos and others is a hoax news that deliberately created or there is a mystery in it.
But you're yourself speculating without ever really thinking about it in a deep way. It's easy to just dismiss things, but sometimes when looking deeply into it you notice that there's got to be something there.
