Earth and Moon Formed Later Than Previously Thought, New Research SuggestsOK, so Earth was created not 4.537 billion years ago but perhaps closer to 4.387 billion years ago. Nevertheless, it just goes to show you that the scientific method is fraught with uncertainty and constantly changes at the whim of whatever the latest "research" suggests.
Astronomers have theorized that the planet Earth and the Moon were created as the result of a giant collision between two planets the size of Mars and Venus. Until now, the collision was thought to have happened when the solar system was 30 million years old, or approximately 4,537 million years ago. But new research shows that Earth and the Moon must have formed much later -- perhaps up to 150 million years after the formation of the solar system.
