Presently, Earth is shrouded in a delicate layer of atmosphere, safeguarding a vibrant planet filled with verdant landscapes, vast oceans, and thriving organisms. However, 4.5 billion years ago, it was a chaotic realm of molten rock and desolation, relentlessly struck by meteors, devoid of any atmosphere. What led to the formation of our iconic blue sky? Stunningly lifelike animations coupled with insights from scientific experts illustrate how the fiery chaos evolved into a toxic orange haze, inhospitable to life as we know it. Experience the moment when the first raindrops fell on the scorched ground, paving the way for life's emergence and the creation of the air we now depend on.
