He's claiming that evolution is not a theory?
Yes, apparently, evolution is the "gospel truth," pardon the expression.
No he's not. It's a scientifc theory, like that for Gravity.
You like gravity, no?
Micro evolution is not a theory. It is a fact. When human aids virus evolved from simian aids virus, that was a fact.
Macro evolution is a theory based on the logical extension of micro evolution and it is supported by a lot of evidence, but has not been proven.
