Around 4.6 billion years ago‚ our universe was born by accretion from the solar nebula known as the Big Bang. As the sun heated up‚ this orbiting matter accumulated and unavoidable mass of larger bodies collide to successively create protoplanets with its own gravitational pull. During this period‚ Earth was nothing but molten rock from the collision with other bodies and volcanoes‚ temperature reaching over 2‚000 fahrenheit. Not only that‚ but Earth then‚ would’ve been toxic to humans and modern
