Ancient astronaut theorists always says yes

[TheRealGuywithoutaMustache]

Nobody truly knows what happened back then. Just keep an open mind that anything is possible.

[ayyoquicks]

At the end of the video he stated “all had a universal language” and before the fall of the giants in the biblical time when they were making Babylon god destroyed the tower and made every language/family etc speak in different tongues depending where they were from and looks like that’s what happened here

I'm betting Earth is a zoo for aliens. The ufos are paying customers on safari.

[icedclips]

My guess they were trying to talk to gods or celestial objects.

[baconbutty]

I always wondered if the gyoglyphs were "welcome to" signs for aliens to know where to land 🤣

[suzannedavies]

Could the swirls be a sign for a wormhole or portal opening of some sort, maybe the ancients saw their visitors coming through these portals/ wormholes that opened up in the sky!? Wow so fascinating

[talesfromthescrypt]

Me: Am I high af rn?
Ancient Astronaut Theorists say yes

[ForwardUS]

You will never fail a date with an astronaut theorist. They always say yes.

Occam's razor is a principal of philosophy that states the explanation that requires the fewest assumptions is usually correct. The most common mistake that this television series, Ancient Aliens, makes is that the audience is to assume that aliens are real, that they came to earth, and that they cleaned up so well after themselves that the only evidence left behind are structures or drawings that human societies were perfectly capable of making on their own. The amount of assumptions required to believe that aliens helped humans in any way are significant and it is easier, and more logical, to believe intelligent human societies drew these petroglyphs.

The video also points to the similarities of some of the petroglyphs in different parts of the world and attributes this to influence from the same person, aliens. Many of the petroglyphs have similar basic shapes, such as spirals, circles, or squares, and the audience is to assume that the natives of the land did not know these basic shapes on their own? The video also questions why would a civilization draw what can only be seen from the sky and attributes this to aliens as well. A more logical argument is that these civilizations believed in a higher power and drew these petroglyphs to appease their god(s).

Overall, this television series, Ancient Aliens, serves the audience "evidence" that does not make logical sense and requires the audience to suspend disbelief in aliens in the first place.

I wondered if they were basically runways and landmarks to use when astral projecting if you are going out extreme far lengths

When I was a child I used to draw one of those mandalas in the first minute of this clip. I've always wanted to know why. I used to draw the square one with the squares in the corners of the square over and over and over again😮 they look just like mandalas my mother still has them

0:54 there are 2 options:
1) these symbols are for other visitors from another world.
2) these symbols are for future humans after investigating the planes

If an advanced civilization that had technology of flight was wiped out, then the stranded survivors would make giant SOS signs on the ground.

[Massi_]

Ancient humans : Let's draw random things to confuse the future generations 😂

[phillip]

It always amazes me how everything ancient man did was for Aliens.
If we have been in contact with Aliens for thousands of years then where are they ?

[christineholloway]

I think the one for this main front is a radar screen, triangle is a ship and a warrior man, who seems to be holding some type of multiple blade sword weapon.

[Lawleet]

Whether it's real or not, what hits me is the graphics 😂

[UpStreamLivn]

Remember when the white guys, came over and destroyed all the Mayan texts? You guys look like your always guessing? Go interview, native ppl.
