Life started very early on, possibly soon after the surface cooled enough for water to condense. We’re in the midpoint of a typical yellow dwarf star like the Sun, and as I said, the Sun’s conditions start changing long before the red giant phase. I don’t see where you get not even being halfway.

I wasn’t claiming man as ultimate, but just the only species I’ve noticed that managed to find a way to escape the Earth’s biosphere (briefly). It won’t happen again. No hubris, just a matter of time.
