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?
