    "Aliens" are just our ancestors from earlier civilizations such as those of ancient Egypt who managed to reach a level of technology where they were able to get off this earth while the rest perished.

    Don't forger to add the word "EVIL" to the promo script. That always draws in more viewers because they're probably religious and they want to see the "evil" stuff.

    John Kennedy was shot twice one by Oswald and the second by the secret service by accident. Watch and learn its all here on the internet . All sightings are and should be taken seriously . When hundreds see something at the same time how come this is not enough to believe. If you have seen something that is unexplained that will be enough . It happened for Me .

    So, I guess those experts are wrong about Aliens visiting. The U.S. Government has confirmed that UFOs are real. So, how much credibility do they have now and how much do the conspiracy theories that were correct have? Conspiracy Clout.

    Totally plausible if not probable that Aliens from a different planet have visited Earth in the past, present and will again in the future. We are in space and sending probes to other planets. Why wouldnt a advanced species from another planet ?

    I'm in Fresno CA. Starting in 2004 I've had 8 different sightings on 7 occasions. All I feel, as awesome as some were all are man made.

    Didn't clinton know there was no u. S. Air force in 1947 .? This was another deceptive way of lying to the kid asking him a question . Depends on what is is and is not !

    I saw a UFO in New Hampshire in 2012. 2 witnesses saw it with me. The 3 of us are certain. When I looked online, it turned out there's lots of sightings here. Maybe they love all our trees, lakes & mountains.

    SOM-101. IMHO, that is what we need to prove. IF in fact that is a real document, it's all the evidence I personally need. If it is true, nothing coming from a government agency concerning UFO's can be trusted. But proof is the burden.

    Regarding the technology advancement timeline, it was also the easiest time in recorded history for scientists and inventors from different areas of the world, to get together with other likeminded people and collaborate together.
