[Frumious Bandersnatch]

Just as with gravity, evolution is a fact.

Ooh ooh.  This is a no-no.  Gravity is a law.  Evolution is a theory.  Neither are facts.  Both have facts to support them.  Additionally, evolution has facts against it.

Additionally, evolution has facts against it.

Examples, please.

Gravity is a law.

The phenomonon of Gravity (objects attract each other) is backed up by a Theory of Gravitation; namely General Relativity.

The phenomonon of speciation is backed up by a Theory; namely the Theory of Evolution.

Both are on equivalent scientific footing.
