Given how quickly modern technology deteriorates, I'm not surprised that we've lost most evidence of past advanced technology. I think past people were generally more intelligent than we give credit for.

I love the comment section of every Ancient Aliens video

I remember Bob Lazar talking about element 115 years ago, and he was sneered at, I don't think they're sneering now.

If there was a naval battle with aliens then the title would just sound something like: Naval fleet suddenly disappeared.

Imagine humanity sharing tech and science developments among each other.

Something going that fast wouldn't have a jet engine to leave a contrail.

I’m so glad they update you video, because every person who work sadly they are not here to see it but we always be remembered, and knowledge thanks.

Can History HD in Poland speed up the broadcasting of new episodes? And not omit some, as was often the case? Greetings from Poland! Great show I've been watching for years!

Imagine having a machine one day that could just scan your body and tell you exactly everything that is wrong with your body. I have un-solved inteston /gi problems that doctors can't figure out and it would be great after all the pain i go through that one day i could just scan my body without the pain to know what is wrong with me so i can have peace of mind knowing how to get better. Hopefully the aliens can give us that kind of technology one day <3

That contrails was the result when Saitama punched a mosquito.. 😂😂😂

*These topics are so interesting to go through*

And to think there are people out there that think it’s just us and after we die we never come back. There’s so much we don’t know and never will. Interesting but creepy as well.

Timeline of technological advancements isn't the only wind that blows
One must factor in the access to materials and various circumstances that factor in to the point

[parapitro]

Earth is far from being the planet we know, and If the Earth is not what we know it to be, imagine what the universe is.

This video on UFO tech is just mind-blowing! It leaves you thinking, what was there before us? Before known or recorded History. Well done! 🖖🤓👍

[ionutzigs]

I’ve said: unless I see it for myself I won’t believe, well I’ve seen unexplained phenomena that left me speechless…

[CryptoBates]

This is awesome how they mentioned admiral bird, flying over the south pole, amazing really

[PanamaSticks]

When someone writes about statues that "come alive", it does not mean they move. It could just mean that they are lifelike.

[SICKBOY]

Why do videos make it sound like a contest battling UFOs? We all know it’s no contest

[jampasurprenant]

Great story this is my first time I learned about this.
