Earth’s First Living Organism

More than three and a half billion years ago, Earth was nothing like the planet

we know today. There were no forests, no animals, and no humans. The sky was filled

with toxic gases, volcanoes erupted constantly, and meteorites frequently struck the surface.

The oceans were hot, dark, and rich in minerals. To modern eyes,

this world would have seemed completely lifeless. Yet, in the middle of

this extreme environment, something extraordinary happened. Life began. Scientists believe

that the first living creature appeared in Earth’s ancient oceans. These early seas

contained water, heat, and chemical compounds—exactly the ingredients needed for life
