Thunderbird and loveritas:
Earth's obliquity is always changing. It is not a fixed constant value. The astrophysical literature contains mathematical models that can be used to calculate our best available determination of what Earth's obliquity was in the past. There has actually been a significant amount of interest in, and accurate determination of, that in recent decades because it is important to climate change calculations (affecting how much sunlight impacts different latitudes, etc.)

My discussion with Starry Night is asking them what method they use to calculate Earth's obliquity in the past, especially circa 12,000 BC. I referenced the publication containing the mathematical model I use to calculate Earth's obliquity. Starry Night has not yet referenced or published what mathematical model they use.
