That's simply false. If you don't believe that science has dogma, open up the first chapter of nearly every biology textbook. Most of them start out by discussing the dogma of science, which is roughly as follows:
- We live in a materialist universe.
- There exists nothing magical or supernatural.
- All phenomena are in principle understandable by humans.
- The scientific method is how we can understand the universe.
There are many other assumptions behind science as well, but these are the ones that most textbooks usually enumerate explicitly. Being assumptions, none of them are provable. And in fact there is good reason to believe that many (or all) of them are wrong, which would essentially make all of scientific knowledge wrong as well. And while specific scientific results are at least in theory subject to being replaced, these general principles are considered sacred and unchallengable.
Science is a religion just like any other. And if you actually look at the principles I listed, they actually look a lot like the four noble truths of buddhism. Different content, but still religious just the same.
