The universe is 13-20 billion years old depending on who you ask.
Earth has been here 5 billion.
That gives us 8-15 billion years of missing time.
Within 100 to 200 years mainstream science will know how to get to the stars so consider a race 1000 years ahead of us, or 1 million years ahead. It would be probably impossible for them to miss us since we probably stand out like a sore thumb.
Here, this the most comphrehensive presentation that I have found on it.
As I pointed out above, I don’t consider it an impossibility, I simply consider it very unlikely that an alien race has visited us, was discovered by the US Government, which has subsequently covered it up for decades.
The technological gap – as I noted before, and you alluded to – implied by relatively common long distance interstellar travel is simply so enormous (in terms of relative advancement, not temporally – a race 1000 years in advance of us from our current era of development is FAR more advanced than for example we are in comparison to our medieval counterparts of a thousand years ago) that chance discovery simply would be so unlikely as to be practically impossible. And a planned contact with just one government is almost equally unlikely, as I don’t see any possible reason for an alien civilization to reveal itself to a human government far in advance of when they would plan to reveal themselves to the entire human civilization.
And it would be their choice – any race that far in advance of us would treat us as superstitious primitives (and rightly so). Why would they consult with one of our primitive governments, and hide themselves from all other human beings, any more than we would sneak into a aboriginal village in Papua New Guinea, and ask the local elders advice about whether we should hide from the other natives?

Haven’t you ever watched Star Trek?? Come on. Get real (g)
Seriously, the evidence is all over the place and the best way to hide a secret is out in the open.
Have you notice how many UFO shows are on A&E, History Channel, Science Channel etc. How you noticed how often they run that movie Indepedence Day? The public is gradually being introduced to the idea of ET’s.
There is no point in the ET’s introducing themselves to the world at large. It would only make it more difficult to do whatever they are doing.
My father who is still alive had a top secret crytographic clearance at Maxwell AFB in Montgomery in the early, mid 60’s. One of his duties was to encrypt/decrypt sensitive cables.
I asked him about UFO’s a couple of years ago and he told me flat out that “quite a few pilots” were killed by UFO’s that they were chasing. He knew this because of the information in the cables. The next of kin were told that they died in training missions.
Have you wondered why we cancelled the last three Apollo missions? The offical story was lack of funds but I don’t buy that. My guess is that they found something there that had to be keep secret so they shut it down..
Have you ever wondered why now, all of a sudden, China, Russia, India and the US are all going back to the Moon? Why now and what for??
As far as hiding themselves from us they don’t do a very good job of it.
One last comment on radio communications. We have had the radio since 1902 when Marconi demonstrated the first transatlantic transmission.
This means that any radio waves from another civilization would have had to pass by in the last few decades when we would have heard it.
My guess is that local civilizations thousands of years ahead of us quit using radio so long ago that there is nothing for us to hear and the ones still using radio have not gotten here yet or have and the government has covered it up.
