There is life on Earth, so there is other life out there too. It would be a very simplistic view to think that there is only life on Earth. Hell the dinosaurs ruled this planet longer than homo's have been here.
Let's follow this train of thought, then.
1. The Sun is a typical star, and relatively young. There are billions of stars in the galaxy that are billions of years older.
2. Almost surely, some of these stars will have Earth-like planets.
3. Assuming the Earth is typical, some of these planets may develop intelligent life.
4. Some of these civilizations may develop interstellar travel, a technology Earth is investigating even now (such as the 100 Year Starship).
5. Even at the slow pace of currently envisioned interstellar travel, the galaxy can be completely colonized in a few tens of millions of years.
According to this line of thinking, the Earth should already have been colonized, or at least visited.
But no convincing evidence of this exists. Furthermore, no confirmed signs of intelligence elsewhere have yet been spotted in our galaxy or elsewhere in the observable universe.
Where is everybody?
This keeps me up at night. The silence from the stars is overwhelming. Suffocating. The longer I think about it, the more horrifying it gets. Are we alone?

Given the distances involved, the limitations of the laws of physics and the conditions and time required to allow for the development of intelligent life it could be possible that civilizations of sentient beings can rise, prosper and fall to extinction without ever contacting one another.
Either that or Aliens have been in contact with Humans all along but we've never known it because of the Illuminati.

I dont believe in that line of thinking. I think the universe is thumping with life, but I dont like absolutes, so I think it is wrong to say that
Also I think there is some proof that aliens have visited Earth. Here is a pic of an Egyptian hyroglific that shows a helicopter and plane.
There are also mentions of aliens in many different civilizations, and the bible mentions of alien encounters. Also there are astronauts who talk about aliens. And I'm sure the gov't knows more than they are telling.

Given the number of stars and planets in the known universe, it is virtually a statistical impossibility that life in some form doesnt exist elsewhere. The odds of there being no life anywhere else are lower than the odds of winning the Texas state lottery four times in the same calendar year with the same numbers in the same order every time.
In other words, for all intents and purposes, there is life somewhere and probably lots of somewheres.

Sol is not a typical star. Red Dwarf stars vastly out-number any other star type.

Earth-sized exoplanets are not the best candidates for life, in fact. "Super-earths," which are 2-3 times the mass of our world are much more plentiful and are more likely to have water and other necessary chemicals for life than do earth size exoplanets.

3. Assuming the Earth is typical, some of these planets may develop intelligent life.
Our only example casts doubt upon that proposal. Single-cell life originated on earth 3.8 billion years ago. However, it took 3 billion years for multicellular life to appear. Sentient lifeforms, us, appeared about 200,000 years ago. By our example, intelligent life is much more unlikely than simpler lifeforms.

In my opinion, we cannot traverse space in our present forms. We must either become cyborgs or create A.I. to travel away from our solar system.

Maybe, but I don't think colonize is the right word. It's just too big even for exploration without some new physics.
