It is in fact the tilt of the earth that determines the temperature along with distance from the sun. The tilt of the earth does not change. Only the position of the sun rays hitting the earth as it revolves. So should the tilt of the earth change, we would burn or freeze to death. Seasons have little to do with the tilt. Climate is what results from tilt. Seasons have to do with the revolving of the sun. Evolution can't explain this, but it explains other things.
If the Earths tilt changes the solar flux would remain the same assuming that the tilt change wasnt accompanied by a change in the distance from sun to earth this means the amount of incident energy/time remains the same the only difference would be in the distribution...
Since all life isnt baked to a crisp at the equator or frozen to death in the polar regions it seems a safe enough inference that life would exist at different axial tilts....
