It seems reasonable that there would be periods when the Earth is just a little closer to the Sun than usual, and you get a warming period for 6-10 thousand years that just happens to be ideal for human life to thrive.
As the Earth re-enters its typical orbit, the temperature falls and the ice returns to replenish the land. Biodiversity flourishes and the circle of life continues.
Just thinking out loud, of course.
We’d need to suffienciently warm the planet via industrial pollution/weather modification to overcome moving notably further away from our star, and that feels like a very tall ask, especially with presumably far fewer people.

There are many cycles that control long term variability. Some we know, some we suspect, some we are clueless about. They have many different time scales, and it's usually when they overlap or interact that we get big changes(if not driven by other Earth bound factors). I think I remember reading about one involving the solar system passing by some other powerful gravitational force. And then there are the one off galactic scale events that won't repeat, but confuse the record. So yes, but there are lots, so you can't look at one in isolation. You could Google it if you are interested.
