Bumi ko rumah bagi jutaan spesies, tamasuak manusia, bumi kini ko manjadi satu-satunyo benda astronomi nan di situ ado kehidupan. Planet ko tabantuak 4.54 billion taun lalu, dan kehidupan muncul di permukaan bumi sekitar satu billion taun. Adonyo biosfir di bumi nan signifikan maubah atmosfir dan kondisi abiotik lainnyo di bumi, mamungkinkan proliferasi organisme aerobik sarato pambentukan lapisan ozon, basamo jo medan magnet bumi, mahalangi radiasi matohari, sahinggo mamungkinkan adonyo kehidupan di darek. Sacaro geofisik bumi, misalnyo sajarah geologi dan orbit, mamungkinkan kehidupan lah batahan salamo periode ko. Planet ko dihrapakan dapek taruih batahan untuak mandukuang kehidupan satidaknyo sampai 500 milyar taun lai.
Kronologi
Urang cadiak pandai kini lah mampu marekonstruksi ulang maklumat rinci tantang maso lalu planet ko. Penanggalan awal tabantuaknyo sistem surya ko 4.5672 ± 0.0006 billion taun lalu, atau 4.54 billion tahun lalu (1% indak pasti) the Earth and the other planets in the Solar System had formed out of the solar nebula—a disk-shaped mass of dust and gas left over from the formation of the Sun. This assembly of the Earth through accretion was thus largely completed within 10–20 million years. Initially molten, the outer layer of the planet Earth cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed shortly thereafter, 4.53 billion years ago.
