We have good understanding of the mechanism of solar activity. We have a good theory to explain every every molecular reaction from a few seconds after the big bang until today.

A more accurate analogy would be what motivated the Big Bang.

[DManA]

Actually a few microseconds after the big bang.

We have good understanding of the mechanism of solar activity.

Well, that's debatable. We actually have a much better understanding of each of the four mechanisms that propel evolution:

1. Selection

2. Mutation

3. Genetic Drift

4. Gene Flow
