The sentence that provides evidence of universe expansion that supports the Big Bang Theory is "Galaxies are moving away from each other." This idea is known as the concept of redshift. Redshift is a phenomenon in which the light from distant galaxies appears to be shifted towards longer wavelengths (or redder colors) compared to when it was emitted. This indicates that the galaxies are moving away from us, and therefore from each other, supporting the idea of an expanding universe and the Big Bang Theory. Scientists have observed this redshift in the light from distant galaxies, providing strong evidence for the expansion of the universe.
