Earth. What is it like four billion years ago?

Volcanoes and the oceans are always in conflict. They frequently hurl magma and tsunamis to one another. The falling asteroids are at the backdrop, making the scenario worse.

There's a salt lake nearby teeming with cowering microorganisms. However, two odd cells, a prokaryote and a eukaryote, share the same vision. That is to experience what it is on the surface.

One afternoon, they share a hug. Suddenly, they become united, evolving.

The new organism smiles at the sun and breathes the toxic air.

What force makes this miracle possible? It's love.
