It's hard, because sometimes I'm told "The science is settled" then other times I'm told it's always changing.

"Settled" does not mean it cannot be tweaked by new information.

It is best explained by Isaac Asimov in his small essay "The Relativity of Wrong"[0].

Oh we know how it works. Science was bought out by Big industry a long time ago and is as much of a religion as Christianity

I don't think this forum is suited to your kind of short sighted opinions. Life is more complicated than your black and white world view.
