Here's everything you need to know about Planet Earth

New Kurzgesagt video tells us everything we need to know about Earth, from how it survived colliding with an object as big as Mars to how it came to support life.

The fact that we're all here, alive, on Planet Earth today is a remarkable feat. At any point in the creation of Earth, a multitude of things could have happened differently to prevent our planet from becoming habitable. Fortunately for us, conditions on Earth (at least on its surface) are ripe for life.

This video from Kurzgesagt tells you everything you need to know about Earth -- like how it was formed, how old it is relative to the rest of the universe, and how the planet's surface cooled enough to allow things like dinosaurs and humans to live on it. You'll also learn how an object the size of Mars collided with a young Earth and helped form the moon, and how magnetic forces from the Earth's core help keep the surface stable.

Check out the video at the top of this post to learn all these things and more, and be sure to keep your eyes out for a few Easter eggs, like a secret underground dinosaur colony and a Tardis floating down the river.
