I want to know the answer to the following question:
What is the name of the era that predated life on Earth?
All the background I'm provided with is that "The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago, during the Eoarchean Era after a geological crust started to solidify following the earlier molten Hadean Eon.". Is that enough to answer the question?
Answer: yes
