Answer:
Regardless of its name, the Big Bang theory found widespread acceptance for its unparalleled ability to explain what we see. The balance of light with particles like protons and neutrons during the first 3 minutes, for instance, let early elements form at a rate predicting the current amounts of helium and other light atoms.
"There was a small window in time where it was possible for nuclei to form," said Glennys Farrar, a cosmologist at New York University. "After that, the universe kept expanding and they couldn't find each other, and before [the window] it was too hot."
A cloudy plasma filled the universe for the next 378,000 years, until further cooling let electrons and protons form neutral hydrogen atoms, and the fog cleared. The light emitted during this process, which has since stretched into microwaves, is the earliest known object researchers can study directly. Known as the cosmic microwave background (CMB) radiation, many researchers consider it the strongest evidence for the Big Bang.
The Indus Valley Civilization(IVC), was an ancient civilization thriving along the lower Indus River and the Ghaggar River-Hakra River in what is now Pakistan and western India from the twenty-eighth century B.C.E. to the eighteenth century B.C.E. Another name for this civilization is the Harappan Civilization of the Indus Valley, in reference to its first excavated city of Harappa. The Indus Valley Civilization stands as one of the great early civilizations, alongside ancient Egypt and Sumerian Civilization, as a place where human settlements organized into cities, invented a system of writing and supported an advanced culture. Hinduism and the culture of the Indian people can be regarded as having roots in the life and practices of this civilization
