In order of proximity to the Sun (closest to furthest), the planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Earth gets just the right amount of sunlight due to how far it is away from the Sun. Why, then, is Mercury not a valid place to live based off its proximity to the Sun?

Mercury has too much sunlight.

If you kick a soccer ball, it gains kinetic energy. However, the soccer ball eventually stops. Where did the kinetic energy go?

It's lost as heat due to friction.
