No collision, no life: Earth probably needed supplies from space
After the formation of the Solar System, it took a maximum of three million years for the chemical composition of the Earth's precursor to be completed. This is shown by a new study by the Institute of Geological Sciences at the University of Bern. At this time, however, there were hardly any elements necessary for life such as water or carbon compounds on the young planet. Only a later planetary collision probably brought water to Earth, paving the way for life.
