With Aliens, I always said that we are Aliens too
I absolutely believe that we are not alone. Some say that there are already 'Aliens' on our planet, but no way I believe that. People that believe that, are more into movies or the TV-Show "V", lmao. That was a heck of a show if you haven't seen that: https://www.imdb.com/title/tt1307824/
UFO's? If that was a case, we would have been attacked anyways with all our resources we got. You know what is interesting @Ruggerxi do you know where Gold is coming from? I find that also interesting:
"Gold is thought to have been produced in supernova nucleosynthesis, and from the collision of neutron stars,[49] and to have been present in the dust from which the Solar System formed.[50] Because the Earth was molten when it was formed, almost all of the gold present in the early Earth probably sank into the planetary core. Therefore, most of the gold that is in the Earth's crust and mantle is thought to have been delivered to Earth later, by asteroid impacts during the Late Heavy Bombardment, about 4 billion years ago"
