Age of Earth

Scientists say that the earth was about 4600 million years. Earth is the only place that is different from the planets we know today. Earth covered volcano spewing hot gas, rock, and water vapor into the air. During the cold surface of the earth, the rocks to harden and form the soil. Water vapor gets cold, then condenses and falls as rain storms are great. Most of the rain drying on hot surfaces. Some were filling the first sea that is almost boiling and such as acetic acid. In place of the oxygen we breathe now, the air filled with toxic gases, like carbon dioxide, ammonia, hydrogen sulfide, and methane.

Scientists who study rocks called geologists. In 1984, the oldest known rocks on Earth discovered by geologists in Canada. These stones are more than 3690 million years. The objects of the first life is very small cells that lived about 3200 million years ago. While the dinosaur lived about 200 to 60 million years ago, but our ancestors who first is gone up to about 4 million years ago.
