The ToE was the seed to a larger movement.

Please justify this claim.

The Big Bang is the beginning.

Incorrect. The Big Bang was a replacement to steady state theory, which held that the universe had existed eternally. It was not, in any way, a result of the theory of evolution. Falsifying the theory of evolution would not, in any way, falsify the Big Bang. Falsifying the Big Bang theory would not, in any way, falsify the theory of evolution. They are not related subjects.

Astronomers discuss Galactic and stellar evolution constantly.

Such concepts are not a part of the theory of evolution, which employs specific mechanisms not present in stellar formation.

Stellar evolution leads us the creation of heavy metals and planetary evolution, which leads to biological evolution. It's all one big continuum

Please explain how falsifying current theory on stellar formation would falsify common descent. Be specific. If you cannot show such a link, then your claim is false.

The fact that it wasn't part of Darwin's original idea is completely irrelevant.

This is correct. It is the fact that the Big Bang is a theory of physics and cosmology that makes it not related to the biological theory of evolution.

Please justify this claim.

How would you like me to justify the claim? The idea that the universe is here as a result of natural causes vs super natural causes is not a new idea and needs no proof. I do not dispute your statement that the Big Bang is not the only natural explanation for the universe though. It's just a popular one due to red shift.
