Studie starov\u011bk\u00fdch hornin uk\u00e1zaly, \u017ee \u017eivot na Zemi vznikl p\u0159ibli\u017en\u011b p\u0159ed 3 800 miliony let. V t\u00e9 dob\u011b byla Zem\u011b velmi nehostinn\u00fdm m\u00edstem. Vzduch byl hust\u00fd a jedovat\u00fd. Na planetu se sn\u00e1\u0161ely komety a meteority.<\/p>\n

Mlad\u00e1 Zem\u011b byla vodn\u00ed sv\u011bt s mal\u00fdmi \u00faseky such\u00e9 pevniny. Mnoho v\u011bdc\u016f se domn\u00edv\u00e1, \u017ee \u017eivot vznikl v jezerech a oce\u00e1nech.
