No. This is simply wrong on a factual level. Science doesn't have dogma. It isn't religion. See? Your ideas fail because you don't have the facts you need to form good ideas.

To the extent we do, it will be because of advances in science. Science replaces its own ideas (that is, in fact, the exact opposite of dogma) using evidence and sound mathematical logic, which is why that happens. Trying to use science to prove the weakness of science is a wonderful indication that you haven't the faintest clue what you're talking about.
