our earth Home to millions of species of creatures including humans, the earth, is currently the only astronomical object we know where our lives are. Our planet Earth formed 4.54 billion years ago, and its life appeared on the surface about a billion years ago. Our Earth's biosphere has significantly altered the atmosphere and other abiotic conditions on our planet, enabling the proliferation of aerobic organisms and the formation of ozone layers that, together with our earth's magnetic field, block out the very dangerous solar radiation, which allows life on land. The physical properties of our earth. as well as its geological history and orbit, have enabled our lives to survive during this period. Our planet Earth is expected to continue to support life for at least 500 million years.
