Pseudoscience, junk science, anti-science
• Skeptics & Atheists
When you try to use the scientific method to build off of false assumptions, you have a pseudoscience. Usually, pseudoscientific proponents don't admit to any fact that could prove the claim wrong. Creationism is a good example of this - evidence against it is met with the claim that it was made to appear that way.
