Ion Microprobe Technology Reveals Earth was Habitable 4.3 Billion Years Ago

A team of scientists led by University of Wisconsin-Madison geologists Takayuki Ushikubo, Valley and Noriko Kita have completed an analysis of ancient minerals called zircons which shows liquid water existed at least 4.3 billion years ago and that heavy weathering by an acrid climate possibly destroyed the surface of the Earth's earliest continents when the planet was a mere 150 million years old.
