Answer:
The early Earth was probably extremely hot and lacked an ozone layer. There was no unbound oxygen on the early Earth. On the early Earth, few things could survive without an oxygen atmosphere. It seems likely that anaerobic bacteria were the first life forms on Earth.
Explanation:
On the geological time scale, recognisable people only appeared at most two million years ago. At least 3.5 billion years, as during Eoarchean Era, when a geological crust began to develop following the earlier liquid Hadean Eon, the earliest conclusive evidence of life on This planet was discovered.
While the Earth saw some significant temperature changes around two million years ago, those massive glaciations that have been churning the continents for the last million years had not yet made their way up from the North Pole.
