ELI5:Why does earth axial tilt dictate seasons but the distance from the sun does not?
gpt
Distance from the sun *does* have an impact, but not as much as axial tilt.

Moving slightly closer to the sun doesn't make a big difference - can you even tell whether the sun's closer or not by looking? (don't look straight at the sun, by the way)

Axial tilt, though, makes the number of hours of daylight in one hemisphere a lot more and in the other a lot less. Having an extra few hours of sunlight during the day makes the day warmer, and puts more heat into the ground, water, and atmosphere so that the next day is warmer, too!
