Answer to Question 1

The Hubble law demonstrates that the Universe is expanding at a rate proportional to galaxy distances. Nearby galaxies have small redshifts, and more distant galaxies have large redshifts.

The existence of the cosmic microwave background radiation is an extra low-level signal, which provides evidence for the release of energy at every point in the Universe at the time of its creation, with a temperature that perfectly matches expectations.

Basic principles of nuclear physics predict the relative amounts of hydrogen, helium and lithium that were created in the big bang.
