Earth has been around at least for billions of years. Our modern existence is only of about few hundred years. It'd be over estimating ourselves to think that a civilization like us never existed on Earth let alone other planets. As the technology keeps on miniaturizing, there'll be a point at which the verbose existence of technology would largely be no longer there. In that state, if the civilization is reset due to some cosmic incident, a tech civilization like us in far future will think about themselves in the same way. We do read about Atlantis like legend and consider them a myth similarly, we'd be a myth for such future civilization.
