Answer:
Generally scientific proofs are required for something to be seen as scientific. Something that is not proven scientifically, may be called pseudoscience.
Step-by-step explanation:
When a discussion arises between facts, data, and conclusions, there may be disagreement regarding what is actual science and what is pseudoscience. It may be hard to research some things that are given as science that may turn out to be pseudoscience and vice versa.
Something may be tested sufficiently in the mind and practice of an individual that they may hold the belief to be true, even though for others, there is insufficient scientific proof or evidence. Opinions may differ at various levels, even in the minds of researchers.
Other statements or conclusions may be held true within much of the scientific community, but there may be arguments about those things. The important point is that someone is able to find scientific proof that satisfies them personally that something is true or not.
Or someone may hold a cherished belief that relies on intuition or spiritual reasoning, but is not scientifically provable. That belief may or may not be true, and some might label such things as pseudoscience. Realize that someone who holds a cherished belief based on non-scientific reasons may take exception for someone call their beliefs "pseudoscience". This can be an emotional topic.
