The thing about UFO's is, we need to stop worrying about little lights in the sky... they could be anything.
Although the scientific community hasn't confirmed the existence of alien life, it has found that the odds of life only existing on the Earth are mathmatically insignifigant.
Of course there are aliens...
Have we been visited by aliens? There are many reports. Are they true? It doesn't matter.
Things can't be proven with secondary information. The only truth is in the moment, and we are unable to represent or even see that truth.
The higest resolution camera may pick up a lot of light, but it still cannot record truth.
Don't bother trying to prove it. You can't. Just be happy that you know it... or are you just trying to prove it to yourself?...
Don't be frightened.
We all know it at some level. Many people are scared to face reality, as it's far more bizzare than they can handle.
Many cultures speak of holy beings from the sky.
Now humanity knows what's beyond the sky, and where you'd have to come from to descend from the heavens.
So now, we call them aliens.
Is what we have said true?
We can never fully know the truth. We shouldn't drive ourselves to distraction in the pursuit.
You will likely never see them. The frightened will likely not accept their existence in your lifetime. Let it be. Move beyond.
Live your life knowing they exist. That's all you can do. That's what you should do.
Be a good galactic citizen.
We are a sovereign planet. We are our own rulers.
Don't jump to conclusions about tiny lights in the sky. It makes you look stupid.
