I would love to say that all the ufos we see come from outer space and have intelligent beings in them. However, after watching many ufos on youtube, tv, and listening to eye witnesses tell their stories, I believe that 99% or higher of all ufo sightings are from earth. Here are my reasons:

1. When I watch these ufos fly away, I hardly see them shoot straight into space. Instead, I see them fly at light speeds across the horizon, float near a high mountain, hide in clouds, or dive into the sea.

2. In most religions, these supreme beings were cast down to earth. Earth becomes their home. So what major reason is there to fly straight up into space.

3. Most ufos look like tin can man or another words: junk. If I was a supreme intelligent being I would not be caught in something that looked prehistoric. I guess these beings that landed on earth had to, Actually, use earth resources.

4. One thing I don't understand is, how come we never see ufos burning in the earth's atmosphere? I saw the ufo leave earth! Did you see it catch on fire when it was leaving earth? Most likely...no.

5. There is not enough facts that prove ufos come from the stars. There is more proof today about government projects and theories like hallow earth than ufos coming from the stars.

Now, I'm not saying that intelligent life does not exist outside of earth. I'm just stating my five reasons that make sense of where these beings come from. I do believe that intelligent life is out there and do show up from time to time, but I do believe most of the ufos we see are from earth.

I would agree with you, maybe not for all the reasons listed. But i find it much more probable that they are black projects as opposed to alien, which is exciting in itself because whatever technology they are using is much more advanced than anything we know of. I also think that whatever group, organization etc etc that developed this technology has splintered off decades ago and is unknown to even the highest ranks in the military, much like i believe a part of the CIA splintered off and went rogue.

I'm not even going to get into this thread because you give credence to the Hollow Earth Theory.

So, you are saying that aliens are definitely visiting our planet?

Even if only .5% were not from Earth.. well...

While 95% of sightings probably all have explanations we can understand, it's that other 5% everyone is so interested in.

4. One thing I don't understand is, how come we never see ufos burning in the earth's atmosphere? I saw the ufo leave earth! Did you see it catch on fire when it was leaving earth? Most likely...no.

Leaving earth won't give the burning effect.
Only when entering the atmosphere there will be increase of air-resistance what gives the burning effect.

The UFO's saucer shape didn't come about until after Tesla's claims and drawings for his flying machine.It was the culmination of Tesla's work. If you notice his design actually starts out looking like a teardrop, or kinda like a Zeppelin without the extras. Then it evolved into the saucer or "stovetop" design. You can't really say 100% of how it worked, but I believe you can accomplish any goals an infinite number of ways. It supposedly used an inertial engine to stabilize the machine. Kinda like the inertial jumping robot, but with 4 arms moving at an unprecedented speed with mechanical precision. That and a "dual shell" seem to make it stable, where the Tesla bulb is used to push it. I think it's waves compressed to a point where it causes air resistance or something like that. They create some "loops" or "ropes" of air that enable the gyro-stabilized machine to be pushed to the said 300m/s

Tesla was truly a superior being, alien?... no evolved maybe, but I guess that would seem alien to the rest of us. Take it like you will, but it's a known fact Tesla only wanted his technology to get out there, and he sent his plans to multiple gov.. In his later life the US gov. took a strong interest in him, and after that point is when America's gov. went truly top secret.

So in light of this information I believe 100% of UFO's are manmade, simply gov. projects. With this Roswell would be a test and the "alien" ship that crashed there would be a test flight, and would explain why the gov. was the first on scene. Interesting enough I've seen advanced Tesla idea on shows like The outer limits that explain magnetic anti-gravity and turning our bodies into light then shooting the light somewhere to be reconstructed... an idea that Tesla liked to play with.

I think it's more than coincidence that these things all started happening at the same time, it's all just human advancement... and over time we will all see it.
