The Cool early Earth (CEE) theory posits that the early planet Earth had a calm influx of bolides and a cool climate allowing fluid water, after the planetary accretion but before the occurrence of the Late Heavy Bombardment in the Hadean geological eon. The Cool Early Earth is believed to have been the state for some hundreds of million years around 4.2 billion years (Ga) ago. This Cool Early Earth theory is supported by supposed water conditions at the creation of detrital zircon at Jack Hills in Western Australia, dated to about 4.0–4.4 Ga ago, some time after the planetary accretion era of the early Hadean. The Cool Early Earth was immediately followed by the Late Heavy Bombardment.

Famous quotes containing the words cool, early and/or earth:
“Beauty sat bathing by a spring,
Where fairest shades did hide her;
The winds blew calm, the birds did sing,
The cool streams ran beside her.
My wanton thoughts enticed mine eye
To see what was forbidden:
But better memory said Fie;
So vain desire was chidden—”
—Anthony Munday (1553–1633)
“I looked at my daughters, and my boyhood picture, and appreciated the gift of parenthood, at that moment, more than any other gift I have ever been given. For what person, except one’s own children, would want so deeply and sincerely to have shared your childhood? Who else would think your insignificant and petty life so precious in the living, so rich in its expressiveness, that it would be worth partaking of what you were, to understand what you are?”
—Gerald Early (20th century)
“It is in these acts called trivialities that the seeds of joy are forever wasted, until men and women look round with haggard faces at the devastation their own waste has made, and say, the earth bears no harvest of sweetness—calling their denial knowledge.”
—George Eliot [Mary Ann (or Marian)
