During the accretion period the earth was bombarded by meteors. A large, near earth destroying celestial body, struck earth, causing a large amount of the earth to be ejected into space. The ejecta coalesced into the moon. large amounts of elements, such as iron, were carried to earth by these asteroids. A large meteor struck earth near Yucatan, Mexico which caused a mass die off and the extinction of the dinosaurs. Earth currently lives under the possibility of being struck by a monster meteor which can cause a nuclear winter and another mass extinction

If an asteroid hits us, it could wipe out most life. The currently theory is that this is what happened 65 millions years ago bringing the reign of the dinosaurs to an end

The Earth was hit by a massive asteroid which caused our moon to form. without our moon life on this planet would be difficult. The moon stabilizes our rotation to a steady 23plus hours. It is responsible for tides.

Our planet probably was created because of the millions of asteroids colliding into one big mass,many scientists believe that life started through the bombardment of asteroids mixing the needed ingredients through their constant crashing into the lifeless earth
