That is, are we the first species on Earth that has had an industrial civilization?
And would we be able to figure it out if we are not?
If We Weren’t the First Industrial Civilization on Earth, Would We Ever Know? - MIT Technology Review - Pocket
How would it affect your views of humanity if we *aren't* the first industrial civilization on Earth?
anomalous artifacts which do not fit the official time line narrative are a common occurrence in archaeology, they usually get filed away someplace and never get studied or displayed
which is one thing
and the megalithic ruins from some ancient time which are so far impossible to replicate all with their own curiosities [like diamond tool cut marks, polish, precision, etc]
evidence of ancient canals all over the globe, radioactive hot spots in India which bear striking similarities to bomb explosion sites. replete with craters, etc.
just these few brief items point to the possibility of some "other" type of occupation of this planet by intelligent beings with abilities that surpass our own.
certainly the truth about these things has not been either learned or disclosed about these things.
and would such disclosure affect my belief system?
well, to some degree, yes, how could such an event not? but not too much I would surmise from what I know right now....but who knows, it depends on what kind of revelation would hypothetically occur, wouldn't it?
