"Ancient Aliens" explores the controversial theory that extraterrestrials have visited Earth for millions of years.

Great to see Mohan sharing his knowledge

I used to think UFOs were a Joke but during the summer of 2018 around 4 AM I witnessed some strange phenomenon and now I'm a Believer 😊

[thvimoj]

The Mayans have said mankind has arisen 5 times in earths history. It is far more believable that ancient technology was created by them. It is also more probable that our civilization has found that technology and reproduced it. There is no doubt that there is a mystery in the archeological and geological historical records. The fact that scientists refuse to look at them tend to give reason to this theory.

After watching this show for 20 seasons I have learned two things:

Giorgio's wardrobe has been consistently Indiana Jones-themed for 20 seasons.
They have not found any definite proof of aliens. I love the show, but I am still waiting for that OMG truly aliens exist moment.

We’ve never been alone.They were here before us.

Sounds can probably whipe out cancer cells with out damaging the good ones depending upon the tone, this is fantastic, I hope this becomes more mainstream,

Crops circles aren't different from Mandalas. One of the same thing looks like it.

[jamiegeorge]

I love Mandalis. So much I love following the teachings of Hinduism and Buddhism some of the best things to come from humanity have come from these teachings and my opinion.

[nevisjackson]

Overnight, my back side was sending me mysterious messages.

[cynthusinfinite]

Love love AA. Can't get enough! Re: the crop circles not just the knowledge of math but the precision tools, ability to create the imprint. A recent thing that occurred on earth I understand was able to change our dee enn eh. I would love to talk to AA theorists about this.

[Lloyd-lyxt]

Put the crop circle design in a sealed tube chamber then send different sounds inside towards it, then record the echo sound it produces. Try this interesting experiment you may find a hidden preforlant that affects one's mind and creativity who hears it.

[kennymilsom]

They are us and we are them. As in time before, as in time afar. As in time right now.

Crop circles so far have limited
communication, as humans have only recognized or understood
a few.
