Our planet is billions of years old. Our current modern society took only 30,000 years to get from stone age to space age. There have most likely
been hundreds of modern societies on our planet over the past several billion years. Each one fading out for whatever reason, climate change, self
destruction, what have you. If the civilization was advanced enough, then yeah, some escaped and made new lives elsewhere.
There is no reason to think that other civilizations have not made it to the moon, or even colonized it to an extent.
Who knows if these building images are real or not and if real, who knows how old they are...
