Explanation:

  • Cosmic Calendar-

This scientific framework compresses the universe's timeline since The Big Bang into a single year.

  • If we consider the universe's estimated lifespan of approximately 13.8 billion years, and hypothesize that human ancestors emerged around 1 PM on this calendar, it suggests that the journey from the first humans to pyramid construction, extending to present times, would amount to approximately 11 hours.
