THE EARTH ~4,6 billion years

Five billion years ago, the universe had already existed for a long time. Countless stars had appeared, were exploded or extinct. The Milky Way already existed in our galaxie, and a huge cloud of gas, dust and rocks (a result from the explosion of stars) took the place of our solar system .

For reasons yet unknown, maybe due to the close explosion of a supernova, the solar nebula condensed, and its temperature rose considerably. 4.57 billion years ago, the sun shone for the first time. The planets needed another couple of million years to stabilize.

Among them was a large ball with a liquid surface which had until then gained only 2/3 of its future size: the Earth.  

地球誕生 ~46億年前

五億年前,宇宙已經存在很久了。無數的星星出現,然後爆炸或消逝。銀河這時已經出現在我們所知的銀河系當中,伴隨著巨大的瓦斯雲團,宇宙塵跟岩石(星星爆炸後的產物),進而形成了太陽系。

至今原因依舊不明,也許是很近的超新星爆炸,使得太陽星雲開始凝結,溫度大量地上升。陽光在45.7億年前出現。之後,經過一百萬年,各個行星分別到達定位。

在眾行星之中,有個表面充滿液體的大球,這時體積只有日後的2/3,即為地球。
