  1. Numerous conditions make our home planet suitable for life. For starters, it has liquid water, an energy source and chemical building blocks like carbon, oxygen, hydrogen and nitrogen. It boasts the right distribution of elements to ensure a hot metallic core and rocky mantle, and a large moon to help maintain climate stability by minimizing changes in planetary tilt. We're an optimal distance from a stable star, which allows the continuous presence of liquid water. Finally, the Earth's electromagnetic field protects us from deadly solar radiation while Jupiter fends off most asteroids.
