Human Beings, do not.

I feel the same way about extraterrestrial aliens visiting Earth as I do about angels and gods. If they exist and are good guys, they would be helping us. If they exist and are bad guys they would be screwing with us.

It could be that they are just observing us, in which case, screw them, they are bad guys. If they are paying attention to what’s going on on planet earth, they are a sorry race for not helping. Come on, give us a bone here.

It could be that they are screwing with us on a monstrous scale and we are not aware of it. If this were true, there would not be such an anarchistic society and Earth society would be living by their plan. If they could control the planet, they would control the planet.

It could be that we are some sort of grand planetary societal experiment, in which case, screw them, they are bad guys. Their experiment sucks and is putting unnecessary and cruel hardship on sapient creatures. It is not possible for an advanced society to let a planet exist in such misery, sheesh, even some lowly humans have recognized the ethical treatment of creatures of lesser intelligence.

Of course it could be that there are no angels, aliens or gods. This would go a long way explaining the situation we find ourselves in, here on planet Earth.

As you can see, the inaction in every scenario significantly indicates that angels, aliens and gods do not exist.

Unfortunately, this also means that if there are angels, aliens and gods, they are the bad guys.
