You're naive if you think that we fully understand the entire scope of human history on this planet. And even more so if you think that there haven't been any technologically-advanced civilizations that predate us.

It only took us a few hundred years to see huge advances in our own technology. In perspective to how old this planet is, don't you think it's more likely that perhaps we as humans really were responsible for some of these "mysterious" marvels of the past?

Are you telling me that extraterrestrial life visited ancient civilizations, a feat in it of itself miraculous with the distances they'd have to of travelled to get here, just to carve some rocks for us?

There are no mysterious marvels of the past.

Something I heard that put technological cycles in perspective for me was the writings of Germanic (I think) people when they saw aqueducts after the fall of the Roman Empire.

They thought it must have been giants who built and used the structures because there was no way humans could have made them.

Spent some time in Egypt, and he's a fucking tool.

Yaw, not sure if it was aliens or us... etc... Your argument is sound. I have yet to see space travel that doesn't require some kind of mysterious Star Trek BS. So I say the crap we find on our planet is us.

And all the monolithic configurations that mirror the 3 star pattern/proportions of Orion. Though that's not proof of anything other than the people who built them understood astronomy.

*interstellar space travel.

Normal space travel being normal.

Also the giants-aquaducts thing. Makes more sense.

I think it’s more likely that, if there are any aliens, they are already here, and they always lived here, among us, or hidden for some reason we don’t know.

Maybe we’re their science project or maybe they’re just us from a distant future or in an alternate universe or dimension, and they keep coming back and abducting us to conduct experiments, much like what the cosmetics industry does to animals.
This would explain why most reported aliens are always humanoids.

There is a lot of stuff out there, 99.99% is hoaxes and fake stuff, but there are other things that are very hard do dismiss. There are reports from a number of very credible individuals and now even governments are starting to disclose several files on these subjects.

Obviously, there are things that are still being kept secret in fear of generalized panic.
After all, nobody wants to hear about alien bases in their backyards, and dissecting experiments on living human beings.

This is working off the assumption that humans were dumber and less capable in the past. And that we are smarter and more capable now. This is backward thinking. Our technology may be superior in many ways, but we as humans are not. They were able to conceive of and implement architectural marvels that we still can't duplicate, using brain power and man power. How could you assume that they would be unable to look up at the stars and contemplate whether or not there are other life forms out there, and then do the same thing we do and use our imagination to draw and write about the what ifs.

there is no explanation of how to move rock inside pyramids that would take 20 cranes of modern today. perfect cut with a fuckin string ? nah something was going on then wether or not it was other life or not who knows. but its all still questions that boggle the mind.

these people worshipped their star gods, megalific sculptures that we cant duplicate in the time frames even in our modern time. believe what you want. ive put a few years into researching this shit and its interesting.

Yeah. Except they had a lot of equipment back then that people assume they didn't have. Like cranes, and hydraulic saws. You don't really hear about that stuff because it doesn't fit the knuckle dragged perception that current human rulership wants us to buy into. If we knew all the facts that have been discovered about those "primitive" civilizations, we wouldn't hold our current culture on such a high pedestal. I've done a lot of research on this stuff too.
