I love thinking about aliens. Of all the possibilities of the many interesting creatures that could possibly exist, I especially like the idea that something exists that is greater than humans. I mean we can't be the top of the food chain. Maybe here on Earth we are, but I don't really think so. Try going out into the African bush alone and see how long you can make it. The reason humans dominate in this world is because of numbers - we can cling together, accomplish a common goal, and we can communicate in a method that other animals can not: Written language.

So let me expand your mind for a moment. Let me explain what and where we are right now. To start off we are on Earth, the third rock from the sun. The sun is a star. A rather normal star. Every point of light you see in the night sky is a star. They are little suns. Sometimes you can see really bright objects in the sky, and when you do those will be planets. But the spots of light that make up the constellations are suns that are very far away. Each little star more than likely has planets, and depending on the conditions, temperature, elemental make up, etc, each star could support a planet that has life. 

Now the common argument is "we can't possibly know that." Well no shit. We can't know anything unless we can directly observe it, however, we have ways of coming to very accurate estimations. It's called math. So let me give you an understanding of what the probability of life being elsewhere in the UNIVERSE is.

Okay, scientists say that there are approximately 100 billion stars in our galaxy. One hundred billion looks like this 100,000,000,000. That's 100 billion. How much is that? Well below is what one billion dollars looks like. Now multiply that by 100 to get an idea of how much paper we are talking about. But we are not talking about paper. We are talking about stars. Really really really freaking BIG flaming balls of nuclear fusion that power everything in our solar system! Our one little sun is like our God. That's why native people worshiped the sun. They understood that all life comes from the sun. So imagine 100,000,000,000 of them in our galaxy alone.
Okay, now that you have a slight idea of how many stars there are in our galaxy (called the Milky Way), there is an estimated minimum of 100 billion known galaxies. Okay so there are 100 billion stars in our galaxy and 100 billion galaxies known. So let me show you what a galaxy looks like. 
That's what the Milky Way Galaxy would look like from a point very far away. See that big huge ball of light in the center? That is the core of the galaxy. At each and every individual point in the center is a cluster of stars, so densely packed the light blurs together to look like a big friggin' blob of butter milk. So the image above estimates some 100 billion stars. Each of these stars has potential to be just like our sun and support life. But that's not all. No where near. The next image that I am going to show you is the most important image that has ever been taken. It is important because it puts it into perspective how firggin' large the Universe is. 
What you are looking at here is the Hubble Deep Field. It is basically a super zoomed-in photo taken by the Hubble Space Telescope that shows not stars, but thousands of galaxies (composed of billions of stars). That's right each colorful splotch of light is hundreds of billions of stars densely packed together. So just quickly counting what I see here I see. Well shit I lost place of my count. But let's just say its an even one thousand. So some elementary math at astronomical levels:(1,000 galaxies seen in this picture alone) multiplied by (100,000,000,000 stars in each galaxy) = 1e14 which is a 1 with 14 zero's after. It looks like this.100,000,000,000,000
That's a number I can't even friggin' pronounce. So let's be very moderate and say 1% of the stars in each galaxy can possibly sustain life. That gives you 1e12. Again 1 with 12 zeros after it. That looks like this:


So that means just in this photo alone there would be one trillion stars that could possibly support life. ONE Trillion! And that is just in this small section of the known universe. 

So now let's speculate there are 100 billion galaxies in the universe. Here's some quick math:

100,000,000,000 X 100,000,000,000 = 1e22

So there would be a total estimated 10,000,000,000,000,000,000,000 stars in the Universe. Yep...

As you can see this is a number practically approaching infinity. 

So humor me and continue reading if I apply the meager 1% of stars could possibly sustain life calculation again. 

That would mean there are 1e20 stars that could possibly sustain life. Or written out only a very small number like this:


But wait that is not all either. Lets assume each star has an average of 5 planets. So 5 times all the stars in the universe gives us 5e22. So there would be approximately 50,000,000,000,000,000,000,000 PLANETS IN THE UNIVERSE!!!!

So let's assume only 1% of planets could possibly sustain life. Wait for it. Wait for it. Waaaiiitt for it. That's 5e20. Again another super long number but for humor I will type it out again.


So to answer the question "Do aliens exist?"

Of course they do.

Besides, we proved aliens exist when we we landed on the moon. Read that article for further thoughts on aliens and how when we landed on the moon, we became the first aliens to factually be known to exist.

Open your mind. We are tiny little meat bags and really not so significant.
