Absolutely - there's no question that it did exist. Despite how the information was initially relayed to us, it's not some vision of a possible future that might come to pass - it's the reality that G'raha Tia was living in prior to his trip through spacetime into the past of the First.

The question is whether it still exists now that it has been replaced.
