I wanted to share some of my thoughts/theories on aliens. and get some feedback from everyone.

First, I feel the universe is too vast for us to be the only intelligent life. The level of that intelligence is currently unknown. It could be at the same level as we here on Earth are. Possibly it could be less advanced. But the most popular line of thinking is that there is intelligent life out there far older and vastly more advanced than the humans inhabiting the Earth. This leaves a few possibilities.

The advanced beings could be just slightly more advanced. Meaning, they may have mastered inter stellar travel, but not much more than that. They would have weapons similar to ours, and communications technology either equal to our own. Or 5-10 years ahead of us. This would fit in with the alleged abductions that take place. They alien species is not advanced enough to outright conquer us. So they study us and our technology. More than likely doing so using small teams consisting of their version of military special forces escorting a small group of scientist. One of their tactics could be flying their craft in a manner which makes them hard to describe in a report as to make the witness seem less credible.

Next is the best possible scenario. The intelligent life out there is advanced millions of years beyond us. But more importantly they are also spiritually advanced far beyond us as well. In this case, the advanced beings will watch us. Helping out discretely along the way. Until our development reaches a point where they can reveal themselves to us. Then begin teaching us to live in a more harmonious manor with ourselves, and with the rest of the universe. And advance our technology as we shed our violent warring ways for a more peaceful way of life.

The last possibility is the most terrifying. A race of beings millions of years of life who have no regard for what they consider primitive or unintelligent. In their eyes, we would be seen in the same manor which we view ants carrying flecks of dirt to build an ant hill. We don't try to teach the ants to be more spiritual, nor do we show them how to build a better home. Most of the time we kick over the ant hill, squash the ants invading our kitchens. We don't guide chickens along influencing their development. Humans raise chickens on huge farms to be turned into meals at fast food restaurants. So the advanced beings would see us. As just another animal. Our cities, ant hills to them. At best they would not give us a second look. At worst, we would be treated like the ants and chickens. They may hold up the giant inter galactic magnifying glass and burn us. They may harvest us and deep fry us. Possibly we could be put to work doing menial labor. Much like how we used to put heavy loads on pack mules. If they were to want to the remaining natural resources of our planet, they could simply bombard us from space. Most likely using weapons which would wipe out all life without damaging anything of material value. Or take a slightly more destructive approach and hurl asteroids at us completely devastating the surface of the Earth.

No matter which scenario turns out to be the right one, it is only a matter of time before we find out. 

That's basically how I feel.
