Answer:
On the 30th of December which equates to 0.065 billion years ago
Explanation:
The cosmic calendar was made popular by a famous astronomer named Carl Sagan. His aim was to help people to better understand when a particular prehistoric event in the universe occurred when compared to another prehistoric event.
He achieved the aim by chronologically arranging the 13.8 billion years of the universe age into one year. According to such arrangement, the Big Bang occurred on the 1st of January (13.8 billion years ago) while Dinosaurs went into extinction on the 30th of December (0.065 billion years ago).
Following their extinction, the age of primates began on the 31st of December (Just 40 million years ago). You can see that Carl Sagan's visualization puts the beginning of primates (which men evolved from) immediately after the extinction of Dinosaurs and very far away from the Big Bang that signifies the creation of the universe.
