You may want to check the Wikipedia article on the Big Bang, or science videos on YouTube, for more details; but briefly, the evidence is as follows:* According to calculations based on General Relativity, the Universe can't remain static for long - it must needs expand or contract eventually.
* Similarly, the Second Law of Thermodynamics doesn't allow a static Universe. Entropy increases; there are irreversible processes.
* The redshift of distant galaxies. The only reasonable explanation of this redshift is that the galaxies are moving away from us. This is related to,but not exactly the same, as the Doppler effect.
* The mix of elements and isotopes in the current stage of the Universe closely matches theoretical calculations based on the Big Bang.
* The cosmic microwave background radiation closely matches that which is expected from the Big Bang model. It is a remnant of the time when the Universe cooled below about 3000 K.
It is a show. I don't recommend for children thought. May be good for adults.
no the no. of stars in the milky way is not the evidence in support of the big bang cosmology.

There are two questions commonly asked:1. Is it real, or did God create the universe ex nihilo?2. Did the Big Bang create more than one universe?3. How can the big bang account for dark matter and dark energy?
It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.

Yes. (See related question below for more information.)

The red shift and the cosmic microwave background radiation was the evidence used to develop the big bang theory.
yes it will happen again after the big crunch then of course, the big munch..... At present there is no evidence that another Big Bang will occur.
Some questions about the Big Bang theory and its implications for the origin of the universe include: What caused the Big Bang? How did the universe evolve after the Big Bang? What evidence supports the Big Bang theory? What are the implications of the Big Bang for our understanding of the universe's beginning and future?
No, it's the other way round. The Big Bang is responsible for the redshift.
He doesn't
