Levi AndersonThe Earth was formed about 4.5 billion years ago by accretion—the clumping together of dust and gas in the early solar system to form larger bodies—a process that has been supported by radiometric dating of rocks and meteorites, seismic wave studies of Earth's interior, and observations of other planets and celestial bodies going through similar processes.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
