A) December
B) February
C) September
D) January

Answer 1

On the cosmic calendar, where every month represents approximately 1.2 billion years, the Sun and Earth formed in September, with the formation of our solar system and oldest Earth rocks dating to that month.

Step-by-step explanation:

Using the cosmic calendar, where every month is about 1.2 billion years long, the Sun and Earth formed in September. This is because on the cosmic calendar scale, where the entire history of the universe is represented as one single year with the Big Bang happening on January 1, the formation of our solar system is dated around September 10th. Similarly, the oldest rocks that we have been able to date on Earth are from around the third week of September, on this cosmic calendar scale.
