The Big Bang theory uses "red-shift" as evidence to explain the beginning of the Universe. How does the red-shift from distant galaxies provide evidence for the beginning of the Universe?

Evidence from red-shift Astronomers have discovered that, in general, the further away a galaxy is, the more red-shifted its light is. This means that the further away the galaxies are, the faster they are moving. This is similar to an explosion, where the bits moving fastest travel furthest from the explosion.

Explanation:

the further away a galaxy is, the more red-shifted its light is. This means that the further away the galaxies are, the faster they are moving.
