"The planet you are sitting on right now, as unbelievable as it seems, slowly pieced together by the collisions of endless cosmic scraps over millions of years. Formed by nothing more than the force of gravity, dust became rock, rock became boulder, and boulder became a molten lump so vast it would pull itself into the near-perfect sphere that we know and inhabit today."
