Is it theoretically possible that an ice age civilization existed that we don't know about (not necessarily "Atlantis" or anything super advanced). I'm wondering mainly if it's possible that people back then could have created a civilization as advanced as say, Babylon for example, and all traces of it have been lost (again, it doesn't have to have sunk beneath the ocean or anything like that). Many ancient wonders have been lost to time and no traces of them exist anymore (Colossus of Rhodes, Babylonian gardens, etc.). So is it possible that ALL TRACES of some civilization have vanished from that long ago?
Personally I highly doubt it. Take a closer look at your two examples: the Colossus of Rhodes and the Hanging Gardens of Babylon were not civilizations but the
products of civilizations. There is abundant evidence for both the polity of Rhodes (part of the wider Greek civilization) and the city of Babylon.
There is every chance that countless bands of hunter-gatherers from the Ice Age left little to no trace of themselves, but there is a considerable difference between Neolithic peoples and the peoples of a true civilization. Any culture that rose to true civilization status invariably left behind traces of itself, due to its sophisticated socio-politics and interactions with other, neighboring peoples. As far as that goes, it's amazing what simple hunter-gatherers left behind for archaeologists to find: everything from the traces of semi-permanent villages to fecal matter and midden heaps.
Think also of the conditions of the Ice Age. Any culture living within the regions that were gripped by the Ice Age had little chance to evolve socially or culturally to something truly sophisticated. The mere act of surviving would've been enough work unto itself.
