Are we the only ones?
Have they already been here or are they yet to come?
...are we the most advanced or are we the least advanced?
The Fermi paradox (or Fermi's paradox) is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilization and humanity's lack of contact with, or evidence for, such civilizations. The basic points of the argument, made by physicists Enrico Fermi and Michael H. Hart, are:
The Sun is a young star. There are billions of stars in the galaxy that are billions of years older;
Some of these stars likely have Earth-like planets which, if the Earth is typical, may develop intelligent life;
Presumably some of these civilizations will develop interstellar travel, as Earth seems likely to do;
At any practical pace of interstellar travel, the galaxy can be completely colonized in just a few tens of millions of years.
According to this line of thinking, the Earth should have already been colonized, or at least visited. But no convincing evidence of this exists. Furthermore, no confirmed signs of intelligence elsewhere have been spotted, either in our galaxy or the more than 80 billion other galaxies of the observable universe. Hence Fermi's question "Where is everybody?".
Are we ready for change? Will we embrace it or rebel against it? Will we be controlled or will we be freed? There are many, many questions and the answers will be forthcoming.

there's only one problem, they can't be extra-terrestrial if they are from earth.
i thought you were going to say neil armstrong and buzz aldrin are the aliens, showing mankind how to get to the moon.
it'll be no sweat for them.

It has been confirmed. There are aliens traveling through space, landing on other planets in our known universe! They have been to at least two locations that we can verify with photographs. These are beings that traveled through space and landed, LANDED on a PLANET other than their own. They have sent out probes and collected data. They do exist. Absolutely, positively, they exist!!
This is a photograph of one of the extra-terrestrial visitors along with the craft they traveled through space in
And this is a photograph of a known probe
Makes you wonder...
As we send probes or even manned flights in the future, will WE become their aliens? Will our wrecked flights end up in THEIR "area 51" equivalent? Will they have outrageous stories about us?
....or, are other, more advanced civiliations on other planets waiting for us to catch up a little more before they contact us?
Are we the only ones? If we can do this what other life on other planets in habital zones are also capable? Have they already been here or are they yet to come? WE did it, are we the most advanced or are we the least advanced?
Everything we know, everything we've been, it's changing on a daily basis. Are we ready for change? Will we embrace it or rebel against it? Will we be controlled or will we be freed? There are many, many questions and the answers will be forthcoming.

We have never landed on another planet. The moon is not a planet. It's a moon.
We sent probes to Mars, which is a planet, be WE have never landed on it.
Why our moon couldn't be planet if it wasn't bound to earth?
Although it's one of the largest moons in the solar system, the Moon is smaller than all the planets except Pluto*. Still, it's so large that if it orbited the Sun instead of Earth, we would call it a small planet and not a moon.
